I have a contract with a roll of dumpster. A 30 yd averages about $375.00 per drop. We put bags and trash in it. We pile all of our brush and heavy install debris. I have a hauling company grapple it into a 57 yd dumpster truck. It runs me $350.00 per load. Also if you don't have a way to pack the dumpster they are not as effective.
