Kate:
I have to admit I'm a bit envious--I have to live on the North Shore of Boston, and can't afford to spend >$400k for a teardown, just to get 1 acre. Glad you've got something in NH. Not sure what part of NH, but have you looked at Meetups?

http://www.meetup.com/Central-New-Hampshire-Permaculture-Group/
http://www.meetup.com/Western-MA-Permaculture/
I know the first one is rather active, don't know much about the other two, but it's a good way to meet
local permaculture-interested folks
Hope this helps,
Michael
