If it is an electrician, then I bet that there is conduit involved, which is only right, metal costs more I bet, not sure though I always use plastic. Plus, a penetration through the foundation into the basement? An interior run in conduit to the main circuit breaker, pull boxes, and outdoor recepticals.

But personally, I think that it is very expensive, do it yourself, at least run the conduit and mount the boxes, it really is not hard. Electricity is pretty easy, but you could save alot of money by doing some of the work yourself, even digging could knock alot off of the bill. As it is, I am a tightwad, and I do all work myself, from fixing cars, to computers, to all types of construction.
