A customer purchased 10 acres of land and had a house built. On an area of about 3 acres surrounding the new home, the excavation company stripped all the topsoil off and put it in 4 big piles around the property. This 3 acres will be rough graded by the excavation company before I come in. There are a few small grades, but nothing I cant get a machine on. I am suppose to come in and take the soil from the piles and rockhound/grade over all the areas, seed, and blow straw. All the areas are able to be accessed with machines, but there probably is a few trees and near driveway that needs hand raked. I figure on using a 40HP JD loader to get dirt from piles and a skid steer with attachments to grade/seed. Ive never done anything over an acre, but wonder what some of you might charge for this and what amount of time you think it would take 2 guys and the two machines?
