I have searched for sod pricing and found too much info. Job is in Wisconsin. Approx. 20000sf of site prep and sod on a hill. Hill is about 30 degrees and along a parking lot, so access is not a problem. Soil is all clay, so it needs some topsoil. Need to get the bid in ASAP. I already bid it hydro, with matting, now they want to see a sod price. I haven't done much sod, so I am looking for advice. Sod install prices seem to be all over the map on this site. Any help would be appreciated.
