Master66, speed is the key. We can rough in 9000+ sqft in a week. We pulled 6000 ft of 12/2 yesterday before 2pm. Five man crew including myself. I usually keep two crews in two places, three men on rough in and two on trim out. We can knock out a 3 bedroom spec house in one day. That's what it takes to make money in residential. All work is to my uniform standard. Any of my guys can make up a 4 gang box w/ one s.p., two three ways and a four way and I can't tell which guy it was. That way who ever comes back to trim out knows exactly what's going on. Labor runs $10-$14 per man depending on time served. We also install LANs and structured cabling for houses with a Low Voltage distro panel we custom build. It offers a lot more than Leviton or PS and is actually cheaper.
