I need help bidding a 3 acre lot with lots of trees and a little hilly. I run a new YAZZOO minimax ZTR 42" 8mph top speed which gets around great in the tight areas. I'd say 1/8 has to be mowed with a walkbehind. It would be myself mowing and another person both trimming and push mowing. I'm guessing about $160. This is my first year and I really want the business. This same person has 3 acres of flat straight mowing I could possibly get, about what should I charge for something easy like that. Please Help!
