All we need to know is the software you're using and what you want the map to contain. In Window's applications we often supply images in the .wmf format, as they print crisp at any size. If you have a postscript printer, one that prints at 600dpi, we can supply either a .tif or .eps formatted image. We do create them, but only client-side image maps. Frankly, they work great and are easy to edit.
Price is determined by the amount of work required.
If you want an image of the USA with every state image mapped, the price will be higher than a simple image with only three hot-spots. Our finished work includes the map and HTML coordinate code. We include instructions on how to place that code on the applicable page.
