Funny, I just used wine crafters for the first time a couple of weeks ago because they had the yeast I was looking for in stock (3726). I came in and the guy behind the counter grabbed the yeast for me while I was weighing/milling my grain. I paid for everything and the prices were extremely...
this guy has done something very similar, I would suggest devoting about 15 hours to reading his website :)

Crooked Stave's Fertile Soil got their hops from
Jack Rabbit Hill Farm (http://jackrabbithill.com/)
So you could try contacting them?
You could also check out the Brews Brothers of Pike Peak, I know a lot of those guys grow their own.
I don't brew a whole lot (nor do I get on Homebrewtalk that often) but the couple of folks I know from BBoPP are great guys. They also recently did a group buy and I think is something they do somewhat regularly. I would suggest checking out their recently updated website...
