Growing Hops?

With commercial craft brewing and home brewing really taking off maybe locally grown hops would be a marketable product.  In doing some research it looks like Michigan State University has some interest in this.  While growing them doesn’t appear too hard, harvesting may be an issue.  For a small hop yard I can’t justify buying some kind of mechanical harvester.  If there was some kind of processing facility nearby then I could take the vines to them and that would address my harvesting issues.  It looks like there is a hop processing facility in northern MI, but I suspect such a processing facility does not exist in S.E. Michigan.  Something for me to do further research on.
