Installing Dedicated Power Lines -- Need Advice

My general contractor is hiring a licensed electrician to install dedicated 20A lines for my audio system as part of a whole-apartment rewire and gut renovation.  While I'm sure the electrician is very capable, I'm also pretty sure he doesn't know anything about audio systems either.  Can any of you recommend a consultant or electrician who specializes in audio electrical I can hire to advise my electrician on how to best set up these lines?

Thanks!
