I have no idea about good paint shops in CT, but here's the process that I went through a few years back to get my '89 SHO repainted in the original black.
I also needed some bodywork done, and I came up with a sheet with what I wanted. It also stated that I wanted a base+clearcoat job ('89 didn't have clearcoat on black) that was better than stock, but not show-quality, as the car was a daily driver.
I had a few shops decline to quote me a paint job, probably because of the black, and that I was going to be picky!
I ended up at the local Audi+Porsche dealer's bodyshop. They quoted $3K for a Spies-Hecker base+clearcoat black paint job. For a color change, I'm sure that you can add another $1-2K to that price.
If you don't get a good recommendation, go to the nearest Porsche/BMW/MB dealer's bodyshop for a quote.
Keep in mind that the cost of materials on ANY paint job is (1) not very high, and (2) a minor part of the entire job. Most of the cost is in the LABOR to properly prep the car and do the job. If you are picky about getting a good job done, IMHO I would not trust any quote below $3K unless you get a detailed explanation of what they do, and a guarantee of satisfaction.
There are no shortcuts, nor any "deals", in getting a great paint job!
