CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation in part of, and claims the benefit of priority, to U.S. Provisional Patent Application Ser. No. 61/330,521, filed May 3, 2010, filed by the same inventive entity. 
    
    
     This invention relates a device for the proper hanging and leveling of shelves, pictures, and other items and more particularly to a hanging and leveling device where the item must be positioned in a level manner either for appearances or functionality and aesthetics. 
     BACKGROUND OF THE INVENTION 
     Typically, it is a difficult task for an individual to position a picture, shelf, or other hanging decorator or functional item that requires a level placement by themselves using two mounting holes. Holding the item (such as a picture or shelf) or a traditional level; marking the spots to place the desired wall mounting fasteners, and then actually mounting the picture in a desired level position, can waste time and be a painstaking task. 
     Furthermore, the individual is many times forced to make several attempts to get the desired hanging object at the proper level or height or to achieve the correct spacing of the mounting apertures. In their efforts to do so, they often mark the walls with a marking device, using a trial and error method, thus creating another job to touch up with paint. 
     In addition to the above, it is often difficult to gain proper visual perspective in hanging new art work with in relation to other existing wall mounted pieces. Often people must lean back to get a better perspective and in doing so might lose their balance and fall. This can be critical if using a taller ladder. An invention that can be used safely on a ladder is a useful invention. 
     It is very desirable for individuals such as art gallery curators, artists, and even homeowners who work with art, shelves, and mounted wall decor to have such a device that will aid them in quickly, safely, and efficiently mounting the objects in the desired level manner without the need for several tools such as a tape measure, level, pencil and so forth. 
     SUMMARY OF THE INVENTION 
     Among the many objectives of the present invention is the provision of a screw mount placement device which can quickly create level marks for hanging and positioning wall mounted items that require two or more mounting screws. 
     A further objective of the invention is the provision of a screw mount placement device which can be handled efficiently by an individual scaling a ladder. 
     A still further objective of the present invention is the provision of a screw mount placement device which can align newly mounted items with those already mounted on the wall. 
     Another objective of the present invention is the provision of a screw mount placement device which aids in securing a level position on or against the wall. 
     Yet another objective of the present invention is the provision of a screw mount placement device is the screw placement guides which allows for the accurate placement of screws based on the measurements of the item to be mounted. 
     Another objective to the present invention is the provision of a screw mount placement device which allows the user to calculate how their object is to be mounted. 
     Yet another objective of the present invention is the provision of a screw mount placement device which aids the user in checking the efficiency of proper vertical alignment. 
     Moreover, a further objective of the present invention, is the provision of a screw mount placement device which allows the user to readily locate the center between the two mounting apertures. 
     These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a screw mount placement device which allows an item to be hung levelly and allows the item to be hung in a desired position relative to already mounted objects.

     Throughout the figures of the drawings, where the same part appears in more than one figure of the drawings, the same number is applied thereto. 
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Reference will now be made in detail to several embodiments of the invention that are illustrated in accompanying drawings. Whenever possible, the same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms such as top, bottom, left, right, up, down, over, above, below, beneath, rear, and front, may be used with respect to the drawings. These and similar to directional terms are not to be construed to limit the scope of the invention in any manner. The words attach, connect, couple, and similar terms with their inflectional morphemes do not necessarily denote direct or intermediate connections, but may also include connections through mediate elements or devices. 
     Now referring to  FIG. 1 , the structure and function of screw mount placement device  100  can be seen. Screw mount placement device  100  has a screw placement measure  124  which cooperates with screw placement guides  108 . Screw placement measure  124  measures the distance between screw placement guides  108 . Screw mount placement device  100  has a level  122  at opposing ends. Also, an optional, but preferred embodiment, is a laser  120  at opposing ends. Lasers  120  aid in aligning multiple pictures, shelves, or other items to be hung. 
     Also, screw mount placement device  100  has center aperture  116 . Center aperture  116  is always directly in center of each of the screw placement guides  108 . This allows the item being mounted to be directly centered over a lower hung object or an existing object on the ground. For example, center aperture  116  can be used to levelly center a mirror over a sink. 
     Also, screw mount placement device  100  has level aperture  118 . Level aperture may hold a level  122  in the vertical position, perpendicular to the ground, to work in conjunction with other levels  122  to properly hang a shelf, picture, or other item to be hung. 
     Now adding  FIG. 2  to the consideration, the function of screw mount placement device  100  becomes clear. Mounted piece  104  is hung on wall  102 . Screw mount placement device  100  uses beam  106  of lasers  120  to align with mounted piece  104 . The screw placement guides  108  are aligned using screw placement measure  124  to ensure a proper distance. The screw placement measure  124  denotes the distance between the screw placement guide apertures  110 . 
     Now adding  FIG. 3  to the consideration, the structure of screw mount placement device  100  can be clearly seen. Main housing  126  and back plate  128  serve as the chassis for the screw mount placement device  100 . Main housing  126  and back plate  128  are secured through the cooperation of mounting apertures  180 , each of which cooperates with its own threaded blind aperture  148 . Each blind aperture  148  receives an assembly screw  182 . In other embodiments, the main housing  126  and back plate  128  can be snapped together, held in place by friction, or any other connection that forms a secure and stable relationship between the main housing  126  and back plate  128 . 
     Main housing  126  has measure window  160 . Main housing  126  and back plate  128  each have cradles  140  which receives level  122  or laser  120 . Level  122  or laser  120  is secured in cradle  140  through silicone  142 , other suitable adhesives, friction, apertures in the main housing  126  and back plate  128 , or any other secure and suitable mounting means. Laser  120  is secured to the main housing  126  through silicone  142 , other suitable adhesives, friction, apertures in the main housing, or any other secure and suitable mounting means. Back plate  128  has right back viewing slot  166  and left back viewing slot  168  which allow levels  122  to be seen. 
     Housing  126  has right housing window  170  and left housing window  172  while back plate  128  has right back window  174  and left back window  176 . Windows  170 ,  172 ,  174 , and  176  allow accessibility and visibility of screw placement guides  108  and wall  102 . 
     Slide assembly  222  is secured between main housing  126  and back plate  128 . Screw placement guides  108  are connected through right travelling line  202  and left travelling line  204 . Right screw placement guide  108  has large top slide  188  which moves in and through small bottom slide  200  for strength and stability. Left screw placement guide  108  has first small top slide  186  and large bottom slide  184 . Left travelling line  204  and right travelling line  202  guide the movement of the screw placement guides  108 . 
     The right travelling line  202  is fixed and mounted in the large top slide  188  with the bottom portion attached to the large bottom slide  184 . By the same means, the left travelling line  204  is attached to large top slide  188 , and the large bottom slide  184 . The first small top slide  186  and second small bottom slide  200  shown in  FIG. 3  also add to the smooth sliding function as the slides glide back and forth. Each of the two guides  108  has a vertical section with a screw placement guide aperture  110 . 
     Housing  126  has right flexible guide  162  and left flexible guide  164  (sometimes referred to as right cable guide and left cable guide) which receive flexible lines  202  and  204  respectively. Flexible guides  162  and  164  are arced to allow flexible lines  202  and  204  to move freely and allow synchrony between screw placement guides  108 . 
     In this embodiment, travelling lines  202  and  204  are referenced. However, this terminology is not meant to limit the scope of this disclosure. Flexible lines  202  and  204  may be replaced by thin metal, plastics, or any other suitable mechanism which is also covered by this disclosure. 
     In this embodiment flexible lines  202  and  204  are depicted as separated and connected through large bottom slide  184 , first small top slide  186 , large top slide  188  and small bottom slide  200 . However flexible lines  202  and  204  may be a continuous piece. Also, flexible lines  202  and  204  may be attached in different configurations and to different areas of large bottom slide  184 , first small tip slide  186 , large top slide  188 , and small bottom slide  200 . For example, travelling lines  202  and  204  may be a continuous line. The top of the continuous travelling line can attach to large top slide  188  and also to screw placement guides  108 . This attachment allows each screw placement guides  108  to move through the movement of continuous travelling line. If the continuous travelling line was not connected to the large top slide  188  or the screw placement guide  108 , there is not synchrony of movement. The synchrony of movement is what allows screw placement guides  108  and screw placement measure  124  to accurately depict the distance between and the distance from center aperture  116 . 
     Housing  126  has to receive large top slide  188  and small bottom slide  200 . Also, housing  126  has left upper slide guide  150  and lower slide guide  152  to receive first small top slide  186  and large bottom slide  184 . Slide guides  144 ,  146 ,  150 , and  152  guide the movement of screw placement guides  108 . 
     Now adding  FIG. 4  to the consideration, the structure of screw mounting placement device  100  is seen. Screw mounting placement device  100  has housing  126  and back plate  128 . Secured between housing  126  and back plate  128  is top slide assembly  206  and bottom slide assembly  208 . Top slide assembly  206  and bottom slide assembly  208  are each attached to left travelling line  204  and right travelling line  202  which can also be referred to as left travel cable  204  and right travel cable  202 . 
     Now adding  FIG. 5  and  FIG. 6  to the consideration, the structure of main slide assembly  222  can be clearly seen. Main slide assembly  222  includes top slide assembly  206  and bottom slide assembly  208 . Top slide assembly  206  and bottom slide assembly  208  are connected through right travelling line  202  and left travelling line  204 . Slide assembly  222  guides the movement of screw placement guides  108 . Graduated measures  220  accurately depict the distance between the screw placement guides  108  and ultimately the screws. Graduated measures  220  are also centered to center aperture  116 . Graduated measures can be inches, feet, centimeters, meters, or any other suitable measurement gradients.
