Richard, I buy whole hops from Seven Bridges, but they are dried. I try to buy a larger volume in July, when they have an annual sale - lower prices plus I save on shipping. I bought 2 lbs. total, divided between Cascade, East Kent Goldings, Hallertauer and Fuggles.
Good luck with your venture, it sounds great! As I said in my earlier post, its really heartening to see North American farmers growing organic hops, since I've been buying them from New Zealand farmers previously.
