i bid a commercial site once before, i just used my residential contract, i lost the bid, someone came in about 35% cheaper. i really didn't care. so, i get a call yesterday for a comm quote. small strip mall, i'd love to get it, it's right in my busy service area, and it will be mowing, ferts, edging/mulch of beds, seasonal flowers. NO parking lot cleanup, AND NO snow. perfect for me. now, of course the mulch, flowers, edging etc will be charged accordingly by the sq ft/cu yd. but as far as the mowing, can i look at it, and think of it like this: " ok, this would be the equivilent to 5-$30 residentials, so, i need $150 a mow." would that be a good way to price the mowing? also, what is the lifespan of an account like this? if we do a good job, can we expect to keep it for years, or should i expect to get bid out next season?
