Unicycling for Cancer Research

im participating in relay for life this year on a team - the event takes place on june 5th-6th in my town. i am looking for ways to raise money for the team im on, and thought i could combine raising money with unicycling. i was thinking i could like get some local businesses to sponsor me on a per lap basis for each lap i do on the school track. i could also get some donations from teachers and students too. so, any other ideas? or is this pretty good?

what should i do to get more people to donate, and about how much per lap should i tell local businesses that would want to donate???
