Something really FUN, not too hard, great team building experience is a spaghetti dinner. I know last year 56 raised $2500 at theirs, and 75 is having one soon. They can be really successful, and apart from getting word out to get money, you are also getting the word out about your team. Your community will remember the great time you provided. Kathie K has a great guide to hosting one in this section of the forums, I'd check it out..
Above all, soliciting sponsors is a big part of it, people will realize your need for money if you have suddenly qualified, and many are more than willing to lend a helping hand. With enough determination, you can do anything.
