Slab Stone Sink Repair

We have a beautiful soapstone sink make of slabs of soap stone. It has begun to leak through the seams and needs to be repaired (may even require some of the slabs to be separated and reglued back together). Is there someone in Brooklyn who has the skill working with stone slabs to do this? (Sorry for the double post. The original accidentally went into the roofers forum and I cannot seem to edit or delete that post.)
