Go to www.criticaldance.com and look in "The Studio" forum for the man who styles himself "2 Left Feet." He posts and replies to lots of messages. 2 Left Feet started ballet a couple of years ago and he lives in L.A., so I'm sure that he could give you some recommendations.
I believe that danceart.com has a list of, and/or links to, dance schools and studios around the world.
Hope this helps.
