Hmm. 76 views and no replies. I'll give it a shot.
Google is your friend. I considered linking to lmgtfy but that's kind of smart a$$y. I Googled "guitar repair Stamford Connecticut" and a boatload of results popped up. One was for a thread in this sub forum asking the same question. I read no further.
If I were in your shoes, I'd Google, then read reviews, then go to one or two selected places based on the reviews and check them out.
Then I'd watch (if I could) while they performed such setup so I could save a little money and do it myself next time.
