I caint help you with the colors that work in North Arkansas, but down here, some of the colors that seem to be working well are black/chartruese, black/pink, blue/white, red/chartruese. But these color may not work up north, the water yall fish is much clearer. Someone from further north would have to help you with the colors up there.
As for jig tie'ers there are several on the boards. I just started a thread on the off topic board to see who all is tying or making jigs to sell. I can think of a few but don't want to leave anyone out, so If they reply to the thread, you can keep checking it for some of the guys to contact.
You can't fish with a hung line!
