I really enjoyed working In the south for NOC. The Chattooga in particular is a great river to work. Really improved my boating. You usually get a cabin to live. NO TIPS.
However working south, middle, north fork of the American was really nice. Weather is great. Sleep in a tent but does not matter. Boating is great. Tips are WAY better. I worked for a small company called Chili Bar Outdoor Center, very mellow and right at the put in. I do not think that it exists anymore. The primo company if you want adventure, lots of different rivers is Whitewater Voyages or Tributary. South fork is a great place to work on kayaking but working down on the toulome is probably more exciting for guiding.
Just Google the rivers and call companies. Many of the outfitts in the west will require a guide school depending on your experience. NOC just trains you. Other companies on the Chattooga are Wildwater, and Southeastern. Both of the later partied a bit more than NOC when I was there but I think we paddled more after work. That or watched "Simpsons"
