ISO bluestone to satisfy landmarks on Brooklyn project

I am seeking 480 sf of bluestone for sidewalk and patio of a brownstone in Brooklyn. Landmarks flagged the use of commercial PA bluestone as not authentic, so have to redo the whole thing using pieces more similar to the rest of the block. Seeking 2″ thick, roughly 48×30 slabs for the sidewalk. Slightly smaller, retangular pieces for the patio. Please let me know if you have this much available and what your psf price.
