I am bidding on a childrens camp that I want to run the numbers by yall. It is a 150 acre camp of which 45 is mowed. It is mostly flat with quite a few trees, 10 cabins, swimming pool, and 5 very large buildings. A lot of the trees wont have to be trimmed due to the grass being dead around it because of the high traffic. The owners are very nice people. The crew doing it now has 3 people on the property at a time. Two on 61" Zs and one trimming. Half is done one week and the other half the next. The owner says they work 8 hrs each time they come(24 man hrs). I will be using a 61" Toro Z and a 44" Toro Z as well as one man trimming. I can operate the 44" much faster around the trees and building than a 61" Z. I figured 50 man hrs X $55 per hr for $2750 per cutting. Do these times and $ amounts look in line.
