I don't know about the legal aspects where you are but seeing how you are a NJATC apprentice you better check your local working agreement. Most collective bargaining agreements prohibit side work as NECA feels you are competing with them. This is a real sore spot with some for reasons I can't get into here. If you would like I can direct you to some forums that you can really get a really broad spectrum of opinions on this.
Maybe someone else can help you with the state laws in Georgia.
