Hi, I'm a sales consultant at Best Buy.
I recommend you go into the store to speak with a Blue Shirt about the possibility of an In-Home setup. Depending on how much work they have to do to mount a TV or just hook cables up it could range from $50-$150 for simple setups or mounts. Again, I would go to store to get an exact quote of what you want done. They can schedule an installation in store as well.
