This home has a floor plan...Basement (down stairs really, cause its finished)Main Level, and upstairs, which are considered "heated area" and falls under the sq.ft. price. The home isn't real big ...about 5000 sq. ft. and will have two 200 amp loadcenters with possibly one downstream 100 amp loadcenter.
I cannot charge for the estimate...else I will loose the job.

I can't design the electrical cause from my experience even the owners don't know what they want until it's framed up and we walk through with a Lighting Rep or Salesman.
I suppose I'll just give a sq.ft price and outline the
extra charges in my format.
I would expect a million dollar home wired in non-metallic sheath cable (romex) to be in the neigborhood of 30,000 dollars. 20,000 for labor and material, around 10,000 for the Lighting package. At least...here in Knoxville, Tn.
3% is generally what you could expect to pay for the electrical portion.
