I have 35,000 sq.ft. of brush clearing to do and have received several suggestions but would like your opinion. The job is a trucking company parking lot 2 strips 700x15 and several other areas. The problem is working around the junk the brush is growing in (bent truck rims, broken cement, wheel chocks, garbage, etc). I know I need the trimmer for the obstacles, but there are some areas that will allow wheeled equipment. Another crew bid $800 on it and the owner thought way too high. To me it looks like about 12 man/hrs x $40 = $480. More if I need to rent something. We also do not have to remove brush, just cut and leave where it falls. Any help is greatly appreciated.
