When I did more of these, we went out and contacted grocery stores, club stores, Sysco, and just about anyone else we could hit up. The key, we found, was to have a list of things that you will need, how many, and a multitude of entry points for donations. If a store balked at giving $250 of pork butts, maybe they could provide $100 of charcoal, or $50 of paper plates, or $25 of napkins etc... But, a clear and easy list, clear and definable goals, and a good explanation of who and why they want to support you.
