Consider attending a few open houses....not for the purpose of finding a home but identifying agents with which to possibly work. You can rely on the recommendations of others but another person may not have a good appreciation for what you are looking for.
First hand informationis always best....and the agents won't even know you are interviewing them!
I know http://www.talkcharlotte.com is a large resource.
Good luck to you!
