Instead of promoting your own brand, you may want to establish a partnership with a coffee roaster that is local. A couple of them that come to mind is Wolf Coffee, located in Rohnert Park, CA and I think it's called Dave and Tom's Coffee. They have their own cups so that they are recognizable. I know that Mocha Momma's in Rohnert Park uses Dave and Tom's, and they have a very recognizable cup (almost grateful dead -esque).
Look them up and give them a call.
Good Luck.
