ISO Used Marble or Granite window sills or slabs

Hi Neighbors, Is anyone looking to get rid of old marble or granite window sills or slabs that are roughly 21in x 5in or bigger? I'm looking for some. I'll check CJ's soon but there were almost none in all of the usual online places (fb marketplace, craigslist, etc). Any leads would be appreciated! Thank you!
