I actually specialize in this type of wiring. The only time I do any other type of wiring is for family and close friends. I have some agreements with several general contractors around here. The electricians they use do not know how to properly terminate CAT5 cable and do not have the equipment to test it. I also do fiber. I do alot of new homes with home offices. On the average 2,000 sq. ft. home, rough in takes 3 hours and trim takes 6. My profit on these is $400 - $500 each. I charge $900. This gets them about 13 boxes each installed with smurf tube (ENT) to a central location in the basement. Each will have 2 CAT5 runs, and one RG6. The coax gets put in at rough in and it tied to the smurf tube instead of in it so it does not take up room. This install also increases the appraisal of the home because it can be said to be network ready and fiber ready (the fiber is a quick pull through the ENT when and if its needed).
