Title says it all. I don't have the equipment or technical know-how to do it myself. The only thing I want is to be able to play import games, I don't care about homebrew or backups. I want to be able to play any game without worrying about region locking, and if at all possible, I want to avoid being banned off of Xbox Live with said mod.

Is there anyone who is in this business that I can absolutely trust and who will guarantee their work? I live in Jersey, by the way, if anyone needs to know.
