What are some ways to raise money for a trip?

Question

OK, so this is my last year at the school I go to, and they always take us on a class trip. (♥Chicago♥) And the more money we earn, the longer we get to stay, and we want to stay as long as we can! ♥ So I need some seriously awesome ways to raise some cash. (we have 26 kids in our class, so it can be a big thing too) And we are all wanting to work together on something. Or maybe it can be something I can just do, it doesn't matter.

It is a Christian school, so it has to be decent.

Thanks for all your help!
