i think, perhaps the easiest way to do it, is use a place like shutterfly or something like that. you can order calendars from them, just upload your photos and presto! you would have someone in charge of collecting, uploading the photos, and anyone who wanted one would just pay him/her and they could order/ship one to you. if it's to be used for fundraising, just charge more than the actual cost, with the net profit going to the charity. of course, whoever was in charge, would be responsible for the $. that's just my 2 cents.
