So I need some help with an estimate. This would be my first big commercial job. I already have a price thought up for the common areas, but its the 247 active lots that i need help with. They are just average sized singe wide trailer lots, I imagine someone would charge 15-20$ to do a single lot. However this is a bid for doing all 247 on a weekly basis. I would be using one 52 zero turn one 60 zero turn and also have two others weed eating for a total of 4 people on the job hopefully would take no more than 10 hours in a single day. This job would include mowing, weed eating around trailers sidewalks driveways, and blowing, I have had someone else suggest $12 per trailer but you do the math that would be almost $3000 per week, I just cant imagine that the trailer park owner would pay that amount, but again I have no experience quoting big commercial jobs, so what do you all think what should I charge per lot for this job?
