The guy that brought in my Albino Cats got them in Arkansas, but I'm not sure of the exact hatchery.
I would call some of the Ark hatcheries...one of them will be able to get them for you, but most may not be too excited about such a small quantity. I assume albinos are very prone to predation so maybe get a few more.
Or you could try this if nobody local can help you.
