We are in the same boat here. We just got the business up and going and already have had interviews with 2 contractors. Trying to figure out how to price. They said there are 4 stages of cleanup. Also wanted pricing for windows. We thought to start at $.16/sq ft, $12/window, then drop $.02/sq ft and $2/window until we get to 4th stage cleanup which would be at $.10/sq ft, and $6/window.
Really kinda lost on how to bid it. Every source we've tried for getting some idea, they mostly don't seem to have a clue, or they do it differently. We're north of Atlanta.
