Hey Mary I actually used to work at Best Buy wayyyyy back in the day. At the time they have a service called geek squad for home installs. I'm not sure if they would be a fair quote for install but if you give them a call they should be able to point you in the right direction.
Not sure about that in all honesty. But I'm sure you CAN find someone on the Thumbtack app if they don't.
