Looking for an audio shop to install rear view camera and hardwire my dash cam

[Grouch]

Sup guys, new member here. I just purchased a used '14 A4 that did not come with a rear view camera so I ended up purchasing one online. Now I'm trying to find a shop to install it and also would like to have them hardware my dash cam while I'm at it. Audio shops are a dime a dozen, so I would like to take my car to someone who knows their way around Audi vehicles.

Thanks in advance!
