Mount one TV on a bracket
About two hours.
Asheville, North Carolina
Service
The common mistake is hanging something heavy on drywall alone. I find the studs first.
I mount TVs, mirrors, shelves, curtain rods and grab bars, using a stud finder, a level and the right anchor for what's behind the wall. In old plaster over lath, I use methods that don't crack it.

What changes the time
Studs, lath, block or nothing. I check before I drill, and the answer decides the anchor and the time.
A big TV or a heavy mirror needs two people and the right bracket. I bring a helper's worth of patience, not a crew.
I can hide a cable behind a plate or a cover. I won't cut into a wall to run new power; that's an electrician's job.

Questions
Only if the wall is solid and the heat is low. If I'm not sure, I won't do it, and I'll say why.
I can use a cover or run them down behind the wall with a plate where the code allows it. New power outlets go to an electrician.
I use a rated anchor, or move the shelf an inch or two to a stud. I'll show you both and you decide.
I'll answer with the hours I expect and whether I'm the right person for it.
