Miss Pat, the dairy and meat goat business is growing in Maine -- sheep dairy, as well -- and there are several groups you should contact. You're already started with Extension Service and Maine Dept. of Ag. I would add:
Maine Organic Farmers and Gardeners Association.
Maine Organic Farmers and Gardeners Association
Maine Alternative Agriculture Association (Ma3), RR 1 Box 1450, Anson, ME 04911-9727, (207) 696-5831 (no website that I could find quickly)
The Homesteading Today website:

has a goat subforum where some Mainers hang out, as well.
Hope this helps.
