Guess it depends on what exactly you're looking for.
Someone to raise the shinogi on belts and then give a finger stone finish on the bevels? JKI can probably do that for you, if they have time to take on a project like that. Evan at Strata could also do it, again, if he has capacity. They're the shops I'd recommend and, personally, I'd wait until they had capacity to do it rather than ship it elsewhere. Craig at CKC I know has the skills, but I haven't seen them take on major work like that previously, but wouldn't hurt to ask I guess.
Looking for someone to raise the shinogi, set geometry on stones, and give it a full stone-based kasumi polish? Almost certainly not. No money to be made in that business, nobody wants to spend the value (or more) of their knife on a polish job.
