If you've already got two clients, the best way to build your business is to give them excellent service and establish a rapport. Then let them know that you've got some space in your schedule and are willing to offer a free trial class to any of their friends/contacts who might be interested. You could even sweeten the pot if necessary by letting your clients know that they'll get two free classes for every one of their friends/contacts that becomes a paying client.
For high end stuff in NYC, the aura of exclusivity and word of mouth is very important.
A friend of mine who did his Spanish PhD in NYC was able to charge 100+ an hour to tutor the private school kids of wealthy people on the Upper East Side. He started off with a single client referred to him by a professor, provided excellent service and expanded it from there. None of these high end people would have hired him from a website or advertisement.

"Me llaman el desaparecido
Que cuando llega ya se ha ido
Volando vengo, volando voy
Deprisa deprisa a rumbo perdido"
