It truly depends on what needs to happen for your particular dwelling/wiring need. For example, my neighbors used their trusty $10/hr handyman, but theirs was more of a plug-and-play type job for a family rooom with drop ceiling and little in the way of in wall wiring or complications. Anything else might put you in need of someone with more specialized skill set and ability. That's not to imply that this is by any means the most complicated type of job- but some folks can barely change a battery, if you know what I mean ;).
DirecTV told me I needed to upgrade my coax in order to have HD service. They would charge $50 per room to upgrade the cable. Is this reasonable? Or would it be better to have an independent contractor upgrade the cable for me and if so, what type of contractor would typically do this? Any help would be appreciated. Thanks!
