Where to find a Justice of the Peace in Minnesota. Can any MN people help me?

I have searched online for a JP in the Twin Cities area, but I'm not having much luck. I am having an outdoor wedding next year, and I would like to find a Justice of the Peace sooner than later. Can anyone give me a referral of some sort if they have used one? Possibly a company name, and maybe how much it cost you? Thanks for your help!!
