I have a customer that wants me to remove a 15' X 63' area of sod on a hill side and install a new bed and mulch everything in. I have never removed such a big area of sod and I'm not sure what to charge him for the removal. I can get a sod cutter for $90/day. About how many man hours should it take to remove the sod and haul it away? Or should I charge by the square ft? This will be with myself and one helper. Thanks in advance for any help.
