Every good application needs a cover letter and a resume.
We won't go into all the details on how to write a good resume, but will recommend any of the excellent books available on the subject. The point we want to stress is that a resume is required. That means something giving us your name, mailing address, phone number, work experience, educational experience and more, printed or typed on a piece of paper or two. Don't send us your resume on a floppy or CD, it takes too much time to load all those CD's just to dig up people's contact information. Also, the resume is not the place to demonstrate your creativity or individuality.
