Been a while since you made the post, I would like to say rabbit rabbit rabbit and suggest locating a nearby farm and get as much manure as you can.
Other sources would be the cooperative extension office for your county and check through their online resources for topics of interest.
Also, you can look for the agronomic service center online and get links to ncda resources.
Your woods will provide hugelkultur materials and checking zones will get your palette of plants to work from.
You will need summer/fall water source so a well or swales and time on the ground to learn the land.
The sand hills seems to be horse farms, golf courses, tree farms and military bases.
Permaculture seems to be able to 'make' poor land productive just not overnight.
Pittsboro has a Piedmont Biofuels and they seem to aggregate many permie 'links' to/around there.
I want to mention bees please
I have collected many links for NC and other permie topics get back and follow up with your progress and I will post as required/requested.
