Commit to purchase a certain number of tickets $20 – $100 worth. Invite donors to make a set donation (i.e $10) to ACS. You pledge 10% of your winnings to ACS and split the rest among your partners.
Guided Tours / Open House
Collaborate with a local landmark or venue that isn’t normally open to the public and arrange a day for guided tours. Sell tickets in advance. Also offer concessions.
