ok, a homeowners association wants a bid for approx 3 miles of roadside mowing and weedeating. the entire 3 miles needs it now but i think once cut, a third will need cutting once every 3 weeks. the roadsides range from six feet plus trimming to 10-12 feet plus trimming on both sides. we are in the mountains so trimming consists of three feet up banks or three feet over bank. i have several p.o.a.'s already but none this size. my question is pricing...per hour, per zone, or some combination? the reason per hour for the first time is to judge how long it will take. i also want to be fair of course and a slightly lower price could get me inside and lead to homeowner upkeep. any experience or advice would be greatly appreciated. my equipment used will be a 48 dedicated bobcat zturn, 1-36 bocat walk behind, and weedeaters.
