The TER search engine allows you to search by ethnicity, so it is simple to plug "Asian" into your search.  You will find a variety of ages, services, prices, and you can make a sound decision.  

Beyond that, about all you might get her is guys shilling for their favorite Asian, and none of them may be what you are searching for.   And, that is not really helpful.  

VIP, search all these are good.

Good luck to you, as for now, my lips are sealed.

Book a flight to Thailand, check in to the Nana Hotel and take you pick of lots, and lots of Asians (about $40-$60 / night).

This is based on my own personal preferences so I'm not trying to offend any local asian providers. Honestly I haven't seen any local asians but they don't seem to be my type.  I've found more attractive asian girls at strip clubs, obviously there's limitations there.  Then there's the indy body rub girls who might do DIY+, I'd recommend exploring the half a dozen or so girls in this category.  I would not waste my time exploring spas because the menu is unclear but I'm sure there's some attractive ladies who work at those too. Next there's traveling providers who may or may not have reviews. These are usually worth every penny but the sad thing is you'll never see them again. The best thing, honestly, is to move or travel to a city with more options.  Thailand might be extreme,  any city with a real chinatown will do.
