After you create and print a composite sheet, this is what I would suggest you do first. I think it makes a lot more sense to create a sample composite sheet first. Simply scan and print the photos along with your name, contact information and your stats on a plain sheet of white paper at a local printer. If the agent loves the shots, then invest in comp cards. If not, then at least you did not waste a lot of money unnecessarily. Some printing companies will require a written release from the photographer giving you permission to make a copy, so ask your photographer for a release that gives you permission to copy the shots.
