Couple seeking established or start up community/farm/homestead in Tennessee/Cumberland

My wife and I are looking for an existing or starting community in Tennessee, Western NC or Cumberland area, to help shape the development of the community. Our dream is a permaculture community on an Ubuntu contributionist model that is also a resource center for people with Autism, Asperger Syndrome, Chronic fatigue, PTSD, to experience a healing and therapeutic lifestyle in a stress-free environment. We have a lot to offer in terms of experience, knowledge, plans and ideas. Clean land with fresh water and fruit trees would be ideal. Please contact us with any suggestions.
