I had an LCO that I know call me yesterday and want me to help him with a large mowing job. He needed my wb for the smaller parking lot islands and other areas, as he does not have one. This looks like about a 12-15 hour job with both of us cutting and trimming. My question is; What is the going rate for subcontracting a job like this? Using my mower and fuel as well as my time. I am just not sure how I should charge for this if I do it.
