Here is a video on redbud and how to grow. They grow over the place in the Ozarks, certainly on Hwy 5 from US 40 and Mansfield down to Ava and on to Mountain Home. I am sure you could find them around Rolla.
Collecting Redbud tree seeds and Breaking Dormancy
Well, you're not near a big town or the county seat so it does not hurt to have machinery to fix your cars. You could help your neighbors out as well.
Good luck with your hazelnuts. Remember, you will need to protect them from the deer. (Discussion at link!)
Habitat Talk hazelnut-protection
The same applies to your chestnuts. IIRC, BenLurkin was involved in a group that was working on developing hybridized Chestnuts. He indicated that they had a lot of problems because the deer would browse them down unless protected in a wire cage until they grew larger.
They sell chestnut trees to hunters for their food plots and call them the #1 food source to attract deer. I'm planning on using tree tubes which will prevent small critter damage. I can do a double row deer fence aka 3D fence around all. Deer freak out about the depth

Premiere Fence recommends 34" high single wire and the double at 20" and 48" high with 3 foot between fences. Should be white poly wire that they can see.
I've got a 80' x 80' six strand electric fenced area that the goats started in. Just need to move the whole thing over to go around the tunnel plus the spot where the hazelnuts and paw paws will be. Swap the high tensile wire for white poly wire and put a single perimeter white poly wire around it. I've got the posts, insulators and just need a $50 roll of braided poly wire.
There will be 30 foot or so between the tunnel and trees which leaves room for some rows outside the tunnel for veggies like potatoes that would take up too much space in there. The neighbor has four new puppies, two of which look like they'll be big, like Great Pyrenees size big. The six strand will keep them out so they don't dig holes in a nice fluffy bed to lay in.
Actually the town I work in is the county seat but it's still just a small town. Two tire shops and neither like it when you bring your own brand new tires for them to install. They're losing out in the markup when you buy from them which is understandable. I paid $400 for these new tires and $360 for the machine. They probably would have charged about $7-800 for the same tires including installation.
I just like to DIY as much as possible. Last set I had put on, I went there at 10am and they said 1pm so I had to kill some time. Then it took over an hour. The helper put one wheel back on and I could see/hear the inconsistency when he tightened the lug nuts with the impact gun. When I got home, I checked them. Two of them I had to use a 3 foot pipe on a breaker bar to loosen, two were about right and one was barely tight. It was basically an all day affair and I had to check all the lug nuts to make sure I could loosen them on the road if I had a flat and needed to put the spare on.
I had the other shop put my rear tires on the tractor rims. I didn't notice it at the time, probably because it's a dark little place, but he put one on backwards. There's a huge arrow on the tire showing which direction it should go. He set me up with two left tires. Can you imagine a tire shop not having a light over the tire machine?
If anyone wants redbud seed shoot me a pm.
I can probably find some to share.
Those things grow like weeds here.
