garden slabs (Gunby NG33)

Is anyone out there looking to replace their garden slabs in the near future please? If so, I would love to give them a new home as a surround for my raised beds. If you have any I can reuse, please contact me asap. I am looking for approx 60, 18"×18" slabs. I can collect within a 25 mile radius of Gunby, North Witham.
