The actual wall mount is easy to install if you go step by step following instructions. I mounted one television, (my first one), just a 40", with some help. Unfortunately on our 70" our location was difficult to reach, therefore we had to hire an outside source. According to Best Buy policy, I'm forbidden to mention the name or telephone number of the company we used, but that route is expensive! I recommend taking a Saturday afternoon with a buddy and doing it yourself. You'll be surprised once you get started how easy it is. Good luck, and I hope I was helpful!
