My GC is a control freak. He does 90% of everything by himself. Literally. The only thing he didn't do is the drywall, the insulation, the plumbing, and the concrete cutting. He did all the framing (with a helper), the electrical, the concrete pouring and leveling, the priming, the subfloor and the flooring and the tiling. He'll do the ceiling install, the cabinet install, possibly the custom wainscoating if the cabinet guy's bid is too high, the painting, and help on the granite install.
