Try asking friends and family for smaller donations. This year, my team (675) lost all of our sponsors. My father and I went out and asked close friends and family for smaller donations of $100 (some were a lot more than that), and they so far have totaled over $6,400
!!!!! It has done a lot for our team, and I'm sure that if you make each person on your team go out and collect a few hundred each you can make enough money to send you to Georgia.
Good luck in your fundraising efforts!
