Just get a decent digital camera, 5-10 megapixels is fine , should run you about 150 bucks, or get one at a pawn shop for less.
get a good portable photo printer, 100-300 bucks depending on where you get one. if you are not using a laptop to edit imges, make sure you get a printer with a screen on it to view and edit pics before you print.
some people use backdrops, check with your colleges or coumminty college's photo or art department on how and where to obtain those supplies.
some photographers just take random pics in the club, and that works as well.
300-600 in startup costs for the camera,printer, and paper, and however much your backdrop and lights run.
hope this helps... good luck!
