OP said "if there is a less expensive way". While full service gunsmith is a great way to go it does not meet that criteria. It also does not allow someone to develop their own skills and be more involved in their hobby.
I have a friend who is full service gunsmith, licensed to manufacture, he does great work and I'm not averse to using his services yet I still like to do it myself sometimes.
