I dealt with some of the same 'stuff' for a long time with shooting Savage 12 FTRs - very few 'smiths work with them enough to be comfortable staking their reputation on it. Doesn't necessarily mean the gun isn't capable, but you may have fun finding someone to work on them.
Similarly, F-class stocks *look* relatively simple - and probably are in the overall scheme of things - but finishing them out to look *and* function well is a bit of a specialty. I found out that out the hard way years ago - if the gunsmith hasn't ever done something like an adjustable butt plate or cheek piece hardware inlet, the *last* place you want them figuring it out is on your new precious. Figure out a way to ask nicely/discreetly if your 'smith of choice has done that kind of work, and how many times.
The gunsmith I've been using the past few years is Shawn Williams of Northridge Rifles, out of Helena MT. He usually does more of the BAT/Borden end of the action spectrum, but he's done work on Savage target actions for me in the past, so he might be game to work with the CdG. If you're only looking for stock work, I might say get a hold of Brett Childress (goes by B'cz on Accurate shooter.com) - he does some *beautiful* work.
One thing that I will say is that availability can vary wildly. I wanted something very specific, so I ordered a custom stock from X-ring. Then I found that the delivery ETA was something like 6-7 months, just for getting the blank to me. That turned into more like 10... which then b0rked the time line with the gunsmith. I literally had everything else - action, barrel, trigger, stock hardware - in hand by the end of July. It was late October the next year before I had it in hand - mainly because of that stock. Was it worth it? In the long run, yes. But if I was in a hurry, you might check out Dima stocks - they tend to have plenty of their standard designs in stock.
