You don't really need the non-profit groups. All you really need is to be able to use their name. So, approach the group leader and offer them a 30% commission if you can SPONSOR them in a fund raising project. They do none of the work.
Next, go to local grocery stores and ask if you can set up a booth outside their front door in order to Raise Funds for the Local High School Band. Sell your books from the booths yourself or hire commisssion sales people to do it for you and give them 20%.
