Unless someone happens to have built the same structure in your area very recently, I doubt you'll get much useful info. Like much of the country, New England is experiencing a construction boom / labor shortage that is driving up construction costs at a stunning rate.
On one hand this is an awful time to build for the afore mentioned reason even if you can find a contractor. On the other, there is no telling how long this will last and whether it be better if the industry slows. The lack of skilled and motivated workers is a chronic problem with no solution in sight. Sorry to be so negative but it's ugly out there.
