Upscale escort agency?

Can someone recommend me an upscale escort agency? I'm prepared to pay a bit more but would really like a classy escort.

I'll be in BA between December 28th to January 4th. I've had great experience during my visits to Colombia where, for 200 US$, you can get a young goddess.

Any help much appreciated.

Yes, please contact the thomaso276 high-end, super-duper, YMMV, escort agency. For 200 dollars we will send you a real classy girl for one hour.

RTFF please. There are no agencies to speak of here.
