There are too many variables to give an accurate estimate. If you have not got at least $500 to $1000 don't even think about it. That is on the cheap side. Your key word was... Install. Expect another 500 to 1000 for professional installation and training.
Thousands if you want anything of substance
There is no “average,” this all really depends on what you want done. The best way to find out is to schedule a visit from their In-home advisor, which will afford you a FREE consultation right in your home, where then they can draw up a several proposals with various options at differing price points. $500 to $1000 would get quite a bit done, considering to mount, set up, and educate for a television, the service is $199. If you want a sound bar installed it is only $50 more. If you want any details you can easily call 1(800)GEEKSQUAD and they can answer most questions.
