Yeah. That had me worried. But I've spoke to guy #3. Took him to the property. Went over everything. The other two guys do a lot of commercial work and "big" jobs. Plus they rent most of their equipment and have a full staff of hourly workers. Guy #3 had his own equipment, and only one other guy working with him.
I've asked around as this guy has done a lot of local work and people swear by him in site prep work. The only thing this guy doesn't do that the others would is getting rid of the trees. He will knock them over but it is up to me to get rid of them. Hope there's a few of my friends needing firewood.
And, that's the way it works sometimes, though I'd still get his Scope in writing. But if this individual is indeed as legitimate as you seem to feel, then it's obvious you may indeed have hit the jackpot with him.
