I live in Michigan. We have always been a design build company up until this year. We have to bid on a few commericial installs, but they all want maintenance contracts figured in to the bid. My question is how many mowings should I figure in per year. I can figure out how much time we will spend mowing, and the fertilizing etc. But to be honest I really never pay much attention to the mowing side of things. I was thinking between somewhere around 35 mowings, but I dont want to undershoot or overshoot the thing. We are going to make pretty good money on the install part, so I just want to give a good honest quote on the mowing side. Any help would be appreciated.
