I'm looking for a reliable handyperson to mount a flat-screen TV on the living room wall. The wall is a plaster board with studs, and I want a clean installation with a proper bracket, cable management, and level alignment. The TV is 55 inches, and I already have a fixed mount I’d like to use. Please confirm wall compatibility, provide any needed hardware, and ensure safety for pets and kids. I’d prefer a time window this week and to have the area tidied after the job.
