tandem kayak available - near Atlanta

Does anyone have a tandem sit-inside kayak (expedition type) that I could borrow or rent for 5 days? I live in Atlanta and could drive to pick it up.

My son, two grandsons and I plan to kayak across Lake Jocassee and spend a few days hiking the foothills trail. We’d like to take two singles and a tandem. I’ve paddled Jocassee a lot and have 20 years experience paddling. I’d be happy to rent and/or put down a security deposit. Many thanks.
