There are lots of ideas in this Fundraising forum. Take a few minutes and look through them and I'm sure you'll find some ideas that will work for your team.
What kind of funding are you looking for? Major source of financial or in-kind support? Then you will want to create a polished, professional-looking presentation and research area corporations and go down that path. Do you need smaller sources of funding to provide your team with t-shirts, travel expenses, etc.? Then other forms of fundraisers like car washes, pasta dinners, etc. may be more appropriate.
Look in the Chief Delphi CD-Media section for white papers.(This will sound like a broken record to some of you) Check out the
NEMO website under Resources for some white papers that might help. Any adult mentor from your team may join NEMO.
