What Nick said.
It depends on all kinds of things; slab foundation or crawlspace, interior or exterior walls, attic access or not, etc.
You're really talking about how much TIME you need to buy, and that's just going to vary from one installation - and one installer - to the next.
Absolutely.
Too many variables to put down a cost depending on the house and requirements of the client.
Our HT probably would have run us about 4k to 6k for complete construction (studs, drywall, insulation, wires, electrical carpet/installation, and wall finishing). It was an empty basement to start, the area about 16x18 if i recall.
That cost would not include furnishings or electronics.
