I would also call the Buildings Manager at Devens to see if they have any single-occupant/shared offices they can lease out.
MassDevelopment manages the property. Give them a call and see what ideas they have for you.
Also, call
CB Richard Ellis about their Wanalancit (pronounced "wah-nah-lan-sit") building in Lowell. My dad's office is there and they definitely have a lot of vacancy. The building is very nice, old mill style with parking and high ceilings. It's also close to UMass and has high-speed (T3?) access.
The CBRE web site has a pretty good search engine too. Here's what I dug up on a quick search.
313 Boston Post Road

The last property has a ridiculously low rate. Either it's a typo or that does not include "build-out". So, he'd have to hire a builder to put in walls and heat and stuff. The others are completely built out for office use.
There's PLENTY of real estate on the market right now. Just fish around!
One more thing...If you want something IN BOSTON, there are at least 4 buildings on my block leasing or subleasing spaces under 2,000/ sqft. Probably for around $30/sqft.
