Don & Pat Stout in Kremlin, OK, just a few miles north of Enid, have Shorthorns. They had about 20 yearlings back in the spring. Just on the other side of Kansas you can find Shorthorns from Lee Bingham of Elbee Farms. He posts on here occasionally under the name "Elbee". I am sure that he can get you taken care of.
Not a breed that you are asking for, but I could hook you up with a handful of black & polled Tarentiase bulls that are semen tested & ready to go to work @ a pretty reasonable price too. Not exactly freaky fronted show bulls, but they are really good quality for Tarentaise, IMHO. Distance might be an issue as we are in western KY, about 6 hours from KC, but I can probably find a trucker easy enough. Let me know if they might work & I can get you some pics.
