I am involved in reinstalling a back yard for a neighbor. 100'x50' (5000 sf). I priced it like this. Sod cutting the existing weeds, raking out the area, hydro seeding, waste removal. I figured it out at labor (600) hydroseeding (400) waste removal (100) total of $1100.00 I think that sounds like a good price. I'd lke to use a skid steer with a harley rake but I think that way was more $$$$$$.
