I also used to do guitar repair full-time and would second what Brian (Roj) said earlier. It's most likely that there's something simple, or a combination of several simple things, that needs adjusting. It's much better to have these checked out first to avoid drastic measures and potentially big bills. Correct guitar setup to suit the player is a skill in iteself and I have worked on many instruments fresh from the original luthier or factory.
