dress maker in NYC area?

Hi brides! I have been searching for a dress for over 2 months and still have not found one I love!
I have been to a ton of stores in LI, NYC and NJ but cannot find a ballgown full skirt with a lace/beading bodice, so I am thinking of getting a dress made. Do any of have experience with any dress makers that you would like to recommend in the NYC/LI area??? THANK YOU!
