Job Here is something to think about. Each treatment Lake Doctor charges $ 0.15 a lineal ft to spray lake banks for Weeds. Do the Math, that is $ 650 an acre, if that lineal ft is 10 ft wide. $ 1300 if only 5 ft wide. AND it is all done sitting down in a boat with a bimini top. Now if it was as easy as I am making sound, everyone would be doing it. There a lot of hoops to jump than meets the eye here. Think a second, Why would I post the prices etc and flood the market? We already have a ton more grass cutters than we need. .
