You have probably seen all of the Black Friday shoppers heading out of Wal-mart with large-screen TVs. Most buyers have never installed one of these TVs on a wall. I talked to one inspector who installs TVs on the wall for about $75 to $100 (plus materials) … taking about an hour. A couple of these installs a week will pay some bills or buy some new toys. Below are some Google search results. There are lots of videos on YouTube … still there are many people who do not have the required skills or materials.
