Colorado Gunsmith for timing S&W cylinder

I have a S&W model 16-4 .32 magnum cylinder I bought years ago, it was new old stock. I finally located a reasonably priced 4” model 16-4 .32 magnum so I sent the spare cylinder off to Hamilton Bowen to be reamed out to .327 magnum. Since I had the spare cylinder I didn’t want to modify the original. I’d rather be able to swap in the .327 cylinder when I want to shoot that caliber. Bowen doesn’t do S&W work anymore so now I need to find a good local gunsmith who can fit and properly time the second cylinder. Anyone have any good local recommendations?

On the recommendation of a dear friend that's had work done there on many guns, I would suggest calling TJ's in Aurora.
