It's a time-consuming job, when done right. The gunsmith charges so much per hour... 40 bucks an hour is typical. - You do the math.
There are some gunsmiths who can do it quickly enough to keep the price down. In the end, it's a decision of paying for the gunsmith's time, or investing your own time. If your time is more valuable than his, then paying the gunsmith is the cheapest way to go.
