My wife and I are considering hiring out the yard repair job, what is a average price per sq. foot that I could expect to pay? The area is about 5000-6000 square feet. The job would include, 1. Getting rid of existing grass and weeds. 2. Bringing in black top soil 3. Grading the soil 4. Planting new seed. I an not sure on how much soil will be needed, there area to cover goes from 0" on both ends to 5 " in the middle.
