Welcome to Hobby Culture Shock.
Basically, Dallas (and Texas a bit more generally) is Hobby Heaven, and you're spoiled. In my experience, most cities outside of maybe the biggest (NYC, SF, LA, Chicago, DC (maybe)) are hobby black holes compared to Dallas, and in those bigger cities you're going to spend a metric fuckton more money for the quality ladies.
It's just the way things are.
As for local hobby resources, in another one of your threads someone mentioned Rate That Provider. I don't use the site myself (I think you have to pay to belong (or at least pay for a useful membership that lets you see the good stuff), and based on some of the people I know that hang out there I don't think it's a good fit for me. Lately, though, it does seem to have the STL hobby scene sewn up.
As for quality ladies, if you have any time left in your visit you might try Naughty Natale:

I've never had the pleasure myself (she upped her rates to beyond what I can afford, sadly), but I've never heard a bad thing about her. And I believe she's a transplanted Texas lady, so maybe the quality of service will compare favorably to Dallas standards.
Cheers,
