Here's what I got: 18 buildings on five acres total (one acre of grass) plus planted areas in front of each bldg, a lot of trees(wall to wall leaves this time of year). Season runs from April to end of Nov. Plenty of hedges and shrubs to trim(twice per season) I start up and inspect irrigation system in spring and blow out in the fall(about 44 zones) Keep weeds under control but they're not real picky. Aerate and fertilize twice a year. Mow and trim once a week. I come up with close to 400 man hours and about $1500 for fuel, fertilizer, and misc.(this doesn't include any spray apps. I don't know what that's going to cost yet). Bottom line: $17,000. I was told by someone once that experts on bidding say to use the 1 cent/sqft/month formula. Which, in this case, works out if you use the total footprint. Your thoughts?
