I hear ya.
Do-it-yourself definitely takes a while. I had to rip out the quarter rounds and run my wires in the baseboard. I also ran flat wires up the wall and taped and then drywall compound to smoooth it out. It has taken some time even though my place is small. The other alternative was getting this local stereo shop and they said it would cost 60/hr and they said at approx. 8-13 hours for my setup.
And I think they hire this carperter that know somethnigs about audio and wire setup. If you want calibration add another 4 hours.
