Well, EagleMed (not Eagle Air Med) has been hiring, but the base selections may not be close to OKC at the moment. Typically 7 on/7 off, so you could commute.
Executive AirShare (thread in the Fractional forum) is also hiring. I think they have had MKC and FTW openings as of late, but they do have an RVS/ICT base, however, commuting would be next to impossible (I'm former EAS) and your life would pretty much suck if you tried.
Those are the only two I can think of. Good luck!
