Customer has 66700 sq ft. 85% weeds. I told him the yard needed to be renovated. soil is clay and a few rocks here and there. I was thinking it needs about 2-3 inches of top soil. I know there's some type of attachment you can rent for a bobcat that flips the soil over. If anyone knows what it's called it would be helpful) all flat ground with a slight incline. Any suggestions for getting this job done and what price range you would charge.
