I am at this moment,taking a break from study material for applicators license.its one thing to know the rules- its another to acually make money following them!!I am working on a bid for several BIG commercial jobs and have no clue how to bid weed control for non turf areas.Should i bid by the sq.' in a price similar to that of turf areas or is there a big difference in material costs, labor etc.?Any replies most appreciated.
