do you have a local gun forum or gun trader site? thatd probably be better to ask than here. youre going to get a lot of recommendations from out of state on here even despite youre request for services in your area.
not familiar with MA geography so I dont know what is local to you but a quick search for "hydrographics worcester MA" turned up a few links
also found a company called Subsonic Hydrographics out of Lynn, MA but no website.
