The whitetail fly tying supplies store is in business. However, Chris Helm has sold the store to Mike Richardson in Geneva, IL. see the link http://whitetailflytieing.com/
I do agree with Alberto that Chris DVDs are awesome way to learn deer hair spinning. I also have the opportunity to take a 6h class with Chris a couple years ago. Man, that was a blast and really helped me to improve my tying with deer hair.
