Winter is a hard time for class II boaters---lots of people at that level aren't yet committed to paddling in the winter (which makes sense because they're still working on their roll and drysuits are expensive) and the rain fills up the creeks so people with class III/IV/V skills have somewhere they'ld rather be: finding paddling buddies can be difficult. But check out the email lists and facebook groups people have mentioned. It doesn't matter if they're actually from your area if you're willing to spend gas money---you need two cars for a shuttle anyway.
If I get a day off sometime soon I would be glad to run the Nantahala with you. I need to go up there sometime soon anyway.
