I am an officer of the Centennial High School Madrigals Choir (varsity competition choir) and we are raising money to go on a trip to San Francisco for a Heritage Festival. We need approximately $16,000 (about 400-500 per person) and we are in need of fundraising ideas. So far we have done car washes, a door to door bake sale, and restaurant fundraising where they give 10-15% of their profit to us. We also have ideas for Goodwill, rummage sale, sponsorship letters, scratchers, caroling for tips, and a few more that I cannot think of.
Does anyone have any other ideas that will result in HIGH PROFIT and that aren't too much work?
