While we were doing a job a neighbor lady drove up and asked if I could give her a bid on removing some rock (1/4" and smaller). I told her when I was done here I would go and take a look. How do you price for removal of rock? Do you charge by the ton or yds you have taken out. It's 360sq. ft. and 2" deep. She wants the rock removed and some topsoil and bark brought in. Thanks in advance.
