You have a better portfolio than most. Stay with it.
I've been in Tulsa three years now and there just isn't that much going on. I'd say put a book together and visit what few commercial studios there are in the area. They won't come looking for you.
On the coasts it is common to have meet-ups for photographers and models. Surf the internet to see if you can attend one in Oklahoma.
Be ready and willing to travel. On MM post an OKC and/or Tulsa zip code.
