What does experience garner on top of being licensed?

You might consider first asking friends if they know of any electricians that have done good work for them in the past. If you've never tapped into nextdoor.com, you might also consider posting on that website and asking for suggestions on reputable local electricians in the area. You definitely want to hire a certified, insured and bonded (if possible) electrician to perform this work. 

If you are going to go to the trouble of running dedicated 120V lines & audiograde outlets to your listening room, may I suggest this:

You may elect to make it a DIY project, but you

a) might require a local jurisdiction electrical permit, and

b) most likely  require an electrical inspection to meet local building codes  regardless.

That is why hiring a licensed electrician is the preferred pathway here.

without an inspection to satisfy local building code terms for a DIY  job, or alternatively hiring a licensed electrician , you are at high risk of violating your home insurance policy and leave yourself at high risk of your insurer refusing coverage in case of an event .
