I had a customer call me the other day wanting a bid on maint. and spraying her nice stand of weeds. She has 1/2 acre lot with the rear chain link fence. There is a drive through gate though. What kind of price is reasonable. Before you ask, I have already taken my Pesticide Applicator exam and know I passed, just waiting on the results so I can get my license. I will have it before I do this job. Do most of you charge by the sq. ft? or 1,000 sq ft.? There is a lot of henbit, clover, etc., etc., etc. I told her it was going to look rough for a while if we sprayed it cause most of the yard is weeds. She was going to get 2 more estimates and make a decision. I am curious what you would charge.
