You should have some good osage in your area. How far are you from Dallas? If in driving distance I'd be happy to help you get a piece of osage bending before you go. My staves are crooked for sure, but we can make a bow turn out as straight as you want. Today's my last day working for the year. I will do some deer hunting, but there'd be several days I could work with you if you're close enough. Be happy to show you how I split osage too, there's lots in my driveway, and would send you home a stave or 2 for when you get back.
There are some bowyers in Oklahoma, Indianguy does gorgeous short native american bows.
One more thing. Check in your area for old osage fence posts. If you can find a straight one with minimal bug damage you'll have the most seasoned bow wood there is.
