We are giving an estimate to a customer in Morris County, NJ for a complete sod job. The price includes 2 inches of top soil, machine rental for 2 days, labor, and of course the cost of the sod. The total area is 6200 square feet. Our estimate is for $6000. Do you think this is a reasonable price? We apprieciate any input you could give us, thanks again in advance.
