I contacted Smith Creek Fish Farm about pricing and shipping for papershell crawfish and they didn't have the shipping costs but would in a new internet page coming out soon.

I have riffraff and an artificial stone reef in my pond that would accommodate the crayfish and make them happy. To develop a clear pond I now have only grass carp, Fathead and Golden Shiners plus turtles and frogs so as not stir up the pond sediment. So if I add the crawfish I will enter into a pond experiment that has less clear water and will have less plants. Then if the pond becomes excessive with papershell I would add a couple of male largemouth bass for some control of the papershells.
