I have 2 upcoming ones as well. both were set up through the either the township or village in coordination with their spring clean up events. they both advertise through mail flyers and through their websites as well. otherwise yard signs strategically located , facebook, craigslist, and a selective email campaign to bigger businesses should help. take your box truck and have a banner made with date and location and have it parked in high visibility places around town, make lots of fliers and have the schools you work with send them home with the kids for their parents.
