I am bidding on a lawn install the property is about 44,000 sqft and it is all rock. I will bring in 200 yds of soil and grade and seed and straw. The front side on the house is a hill so the customer wants a french drain put in to carry the water away from the house. It take me about 3 days to complete I will be using a small dozer and skid steer with a harley rake and a straw blower. I bid $7,500 Does this sound about right????????
