Old school way was to put an ad in the village voice in NYC but doubt that will work much anymore. But that site has adult models listed there. You do have to pay to get the model listings sorted by area etc. A free search will give you every dam model wanna be tht was told by her/his mom they should model. I have seen some pro adult models listed there. Jesse Capelli used to be listed there dont know if she still is. Hope this helps.
