Getting revolver barrel work done locally is a crap shoot.
MOST local gunsmiths don't have the correct tooling to do the job right, and without possibly damaging the gun.
Many local gunsmiths have no idea of what the actual proper procedure is, and don't do critical items like re-cutting the forcing cone to the right spec.
While there are local people who are very good, you really have no way of telling if they are or aren't.
I recently heard from an ex-customer who took a Ruger in for a longer barrel.
He had heard rave reviews from local customers of this 'smith, and the 'smith assured him that he was "factory trained" and "had all the right tools".
The 'smith offered to do the job that day, since this man was from out of town, so the customer decided to wait.
He needed to use the rest room, and on the way back saw that the "gunsmith" had his Ruger locked up in a ordinary shop vice with some wooden blocks, and was just about to start twisting the frame off with a hammer handle.
Needless to say, THAT ain't "factory training" and the man took his Ruger and left.
There are some nationally known pistolsmith's in Ohio, but they specialize in custom work, and are month or years behind.
My advice, unless you can find a VERIFIED expert, sent it to S&W.
They'll do it FAST, RIGHT, and the price will be very competitive.
