A friend of mine runs a frame shop, so I'm gonna put in a plug for him: http://www.baldwinhillframing.com/store/index.php
IMO he's pretty good at what he does, from what I've seen of his work.
They're in Natick, so that might be a bit far afield for you, and I'm not sure if he does this kinda thing. But the shop is walking distance from the Natick commuter rail stop on the Framingham/Worcester line.
Shameless plug
