Sounds cool man....you will have a blast here. It would probably help people if you indicated what class boater you are and years of experience.
Another idea is hit up a few shops, when you get here and typically they can hook you up with some boaters for some river fun.
Also when you get here, post your dates of availability to the Trip Planner section of the boards and more than likely you'll get several replies.
MODERATORS: you may want to move this thread to "Trip Planner".
Happy boating and be safe.
