Maybe a bit unrelated since I have an AGP but when we hired a guy to do grading for it we had a spot that was clear and nearly level picked out but it was a good ways from our house. We thought that was going to be all we could afford to do it there. He suggested we clear and grade a wooded area much closer to the house and said he'd do it for 400 bucks. We said sure go ahead!!! By the time he got through he stood there hemming and hawing and talking about he underestimated the job like he expected us to ask him if he wanted more. Needless to say, my wife wrote the check out for 400 bucks. I felt bad but it was his mistake, not ours. Good luck on your build Sunbaby!
