-Bakesale
-Parties (if you are allowed to have them...not sure on this one)
-talk to local resturaunts about coupons you could hand out for them and get a percentage of the money from the people who have them
-For the summer/good weather, you could hold some sort of games and charge an admission fee
-Culture Show
-Date Auction (although I am personally not for these b/c of obvious reasons...but you could auction off like an actual date...say tickets for 2 to a game or something)
Umm, those are just some from the top of my head...
