Hi Willman...I'm a Minnesotan too. Have you checked Craigslist? I have found some listed there, however not in my area. There is one available in St. Paul Park. Apparently a caterer just left it. Pm me and I will get you the phone number. I know it's quite a distance from you, which is what I'm facing. There are numerous places for a store front. Can be spendy.
I guess I would recommend Craigslist...follow some links posted there for places that serve commercial properties rentals and purchases. Eventually you'll find something that will work for you. Another option would be to send out letters to various commercial kitchen facilities with your requests. All they can do is say no.
Good Luck...I'm looking too.
