I would like to put my tv over my fireplace. However currently the cable input is currently on a side wall which is an exterior wall. the fireplace wall is also an exterior wall. The fireplace has no power outlet on the wall either. Cable is on west wall while fireplace is north wall. Where do i start, reputable company that can maybe do it, what kinda price we looking at? I have seen commercials from directv for wireless connection but didn't pay attention. Would still need somw power obviously.
