I have a job to do the following: 1. remove dead lawn 2. grade remaining areas and level with whatever topsoil needed to go below the new incoming sod. 3. i will then have to spread the soil and lay the sod (approx. 4100 square feet) how much does this type of job run. i never priced this type of job or took on this type of task. how much fresh soil goes underneath the sod, and is this type of job a difficult task.
