Illinois non-resident permits are all sold out for next year? Not hardly! I don't know of anyone that has purchased theirs for next year yet, CD. I don't even think they've went on sale yet. Last year they didn't sell out until mid-August, and I'd be willing to bet they last longer this year -- maybe into the season -- because they doubled the price of them.

Even though I live in Missouri, I can't be of much help on where to go. You're right to look to Northern Missouri though. Stay above I-70 and you'll be fine.
