Private Teacher Question?

Hey guys ^.^ I'm a young violinist looking for a private teacher. I took lessons from a teacher before, but I moved recently so I must find another. I see that many members of the ASO (Atlanta Symphony Orchestra) teach privately. I am interested in lessons from on of these people: David Arenz, Judith Cox, Justin Bruns, or Ronda Respess, however, I'm not sure how I would go about contacting one of them or what qualifications I must meet for them to teach me. I know it's a tough question, but could someone help me find a number or an email address? Thank you so much x)
