What about searching for reviews on this website?

With the recent changes at BP and the increased use of that site for LE stings, scams and other bad behavior, I stay away from it.

You can search TER reviews by TS and some sub-sets of characteristics; or you can just search for TS providers in an area. If you're in a "provider desert" (no reputable providers in your area), you might need to travel to the nearest Big City to find what you seek. I'm in the same situation myself, with the nearest Big City a 4 1/2 hour one-way drive, so I'm limited to being able to play to 2-3 times a year.

Search the reviews for a TS provider in KC and see what your options look to be -- you might a good reason to make the trip.

Buena suerte!

any situations where the girls weren't independent. From what I've seen TS girls rarely work for agencies or AMPs. They may have a man, woman, or another TS in there life who is a partner in the game, but I don't think lack of independence or full control is much of concern.  
The living in a place where there is no action is tough. I echo the other comments regarding travel and doing research. I've driven 7 hours one way to see a specific provider. You can imagine the pressure that puts on the encounter. All that work and suspense building up. My advice is to formulate a plan A, B, C, and D for your out of town adventures - and just be loose and open to whatever works out.

That's my situation.  Along with a few other issues, it means I only get to play when I travel.  I make the most of it though with research.  I have fun and value the experiences more.
