I have to complete a quote for 5,150 sq ft sod installation. Firstly, the client would like us to install 7 underground gutters(15 feet long) and we figure to charge $100 a pop. He would also like us to add some soil (4 yards so looking to charge $340.00) and grade the lawn. We will probably rent a bobcat for the grading. To install the sod I'm thinking of charging $1.00 per sq ft. Just wanted to get some opinions if these prices sound fair. Any feedback would be greatly appreciated. Thanks.
