Replying to Naked Calendar!!

Hey guys basically the team I play rugby in are thinking about doing a naked calendar (not aloud to show genitals which sucks) we need to do it kinda sharpish for multiple reasons. Does anyone know how you go about this? As in what company do we go through like can we get them made cheaper if they are for charity so we can give more money to charity? We have already got a really good photographer. Any help and or sarcastic comments would be appreciated.
