I can price yard clean-ups and such but I am bidding on a job that I just don't really know how to price. Its a clean up job sortof but it is mainly hauling off rocks. All different sizes from fist size to some that will take two people to lift. How many rocks? If I was just using a pick up truck ( which I am not I have a trailer) it would be several trips to the landfill and back. It will definitely be an all day job, the dump is probably 15 minutes away, still have to unload the rocks. I don't have a dump bed. Should I rent a bob cat to move the rocks or just use wheel barrows? What should I charge just for my labor? $400, $500?
