I'm not sure about Waynesville specifically, but there may be some
permaculture types in Rolla and almost certainly in the Springfield area. It may be a shot in the dark, but finding and contacting your local university extension office may bear fruit.
Also, communitycommons.org is a free site in partnership with the University of Missouri (or had its initiation with the university, I don't really fully know the back story). But it's an excellent mapbuilding resource- sorta like Google Earth, but with the ability to add agriculture- oriented data layers. You can find the soil type boundaries for anywhere in Missouri and their associated features- whether there's a claypan impediment to
water movement, suitability for
hay and other agricultural crops (I know blackberry, elderberry, and most common garden vegetables are on there), and suitable tree species for the soil type. There's a ton of information which may help you build a plan.
Good luck!
