Hi! I'd like to create a sort of E-bay web site of sorts for my high school, just so that graduating seniors or people who are done with their classes could sell their SAT or AP study guide books. I'd like to have the functions of a timed bid, as well as requiring specific information from registered users (like home/cell phone numbers, homeroom number, real names). But after the bidding is done, I'd like them to handle the money between themselves (eg they meet at school and exchange) rather than using Paypal or credit cards or checks, since minors would be using the it. I'd just like to make it as hassel-free as possible for students to exchange used study guides for whatever (they may even barter!). But I don't even know where to start... help?
