I'd be hard pressed to believe any hunting guide in any state offers guaranteed successes for bobcat - Coyotes are almost a sure thing given a couple days of hunting and proper preparation, but cats are a different game. I can be sure in Kansas that even hunting in "cat rich" areas, there are no guarantees, not even "high likelihoods". I have a couple spots in Kansas where I'll see cats regularly, but getting a shot on one at that spot might take multiple visits throughout the winter.
The only time you're really able to improve your odds is to hunt right after a fresh snow in an area where cats are thick. That lets you confirm fresh track and limit your hunt to where you know they are "right now". Which - consider what that means too - there's no real way to schedule your hunt around opportunity to snow, especially in Kansas or Missouri.
There are plenty of hunting guides that will give you a good coyote hunt with a good chance of bobcats. If you're OK with that kind of hunt, then call a few outfitters, ask around if they have spots along rivers/creeks with good timber cover and high deadfall or brush piles. Brush-piles in hedge riddled pastures with nearby water tend to be my hottest opportunities for cats.
This year should be a good year for it. I've been seeing more cats this year than normal.
