Hi A, I would ask friends and coworkers for good experiences they may have had. You can also use somebody like me who, although in Philly, have contacts in Charlotte and know what questions to ask. So I can so the phone interviews for you and give you a name.
I know www.talkcharlotte.com is a large resource.
Good luck to you!
