Welcome to my neck of the woods, we are about 2 hours from Wilmington.
When I moved my gals from Ohio to here in NC I made sure that they where updated on their shots and also I had the farrier visit right before we left, this way I had some time to find me one here. Also I picked up about 1 month worth of the feed that they had there, just in case I was not able to get the same thing here and I also picked up 1 month worth of hay so that I could keep them on the same hay and gradually get them used to the hay here.
My guys are in a 20 acre pasture that is surrounded by 150 acres of woods and I have had no issues with snakes in the 5 years that I have lived here and rented my pasture.
Not able to recommend a shipper as I shipped my gals myself.
Hope that you enjoy NC
