Try Robert Harper who is a member, and posts on this forum. I think he lives near Hartford, CT.
There are other growers in Connecticut...maybe they will chime in like Gabe in West Haven.
Cuttings: Try asking on this forum for varieties that will do well in the Connecticut climate, but also mention how you will be growing your trees, i.e. in ground, in containers, and also, winter storage. This matters.
Good luck.
