Definitely can't help you there. I found my builder near Littleton using a variety of sources. Referrals on realtor's websites, social media, scrolling through google reviews, and driving around looking at who is building what.

There is also this: https://nhhba.com/

While it is not all encompassing, if you go to about-->member directory, you may find reputable locals. Direct link, here: http://business.nhhba.com/list

Obviously still have to screen those folks, but it's a start point.

*Finding a builder is somewhat of a nerve wracking experience.
