I just installed a couple of Dense Yew's on a customers property. The cost of the bushes were $20 each plus tax and the topsoil and peat cost another $20. It took me an hour to install them and about an hour of my time to go buy the supplies plus about $10 gas. So I've got about $70 total invested plus two hours of my time. My labor rate is $30 per hour so should I just add $60 and charge $130... just wondering how you guys charge for this type of work?
