Range Rental

Hoping someone here might have a good connection. I'm looking for an outdoor range to rent for two days somewhere withing 1.5-2 hours of Charleston. I need to host a small carbine class for a group of friends. PGC won't rent out bays and the public ranges are a definite no-go. I need to go back to at least 50 yards and have a good safe impact berm. Any help would be appreciated.
