woodsy venues in piedmont of North carolina?

I'm looking for a venue to hold my "enchanted forest" themed wedding may of 2017. I'm looking for a pretty landscape with plenty of trees and maybe some type of lake or pond nearby and some kind of building or shelter in case of rain. Somewhere in the piedmont of North carolina. I have come across a few but the venues have either been too expensive or won't allow me to bring my own catering. I'm trying not to spend over $1000 for venue if possible. Can anyone make suggestions???
