Im use to push prices by depth. That makes it easy for me and no dispute about how long your there.The bid wasnt real specific with what rates to include. I'm going to throw in other rates for equipment that might be used. I would have to put a 3-4 hour minimum cost for anything that I have to rent.
I have a 8' blade with a tailgate spreader and a 6' 1/2 blade. A couple 2 stage blowers and a 4 wheeler with a 4' blade.
