The Quest For Fur

I have a convention coming up here in April and I've taken it upon myself to have 2 fursuit heads done in time for the convention. Money isn't an issue, what is is finding the different shades of brown and grey I'll be needing for both heads. I've looked through some of the larger fur providing sites and so far I'm not finding much that comes close to the four browns and two greys I'll need..

Here are the colors:

I actually did manage to find this really nice chocolate brown from fabricempire.com has anyone used this brown? http://www.fabricempire.com/faux-fur-shaggy-chocolate.aspx
