Offcuts of sandstone paving slabs/potential hardcore (Mimbridge GU24)

I have a pile of about 50 offcuts of sandstone paving slabs of various shapes. The slabs were originally 60 cm x 60 cm (2 ft x 2 ft). They could be used as they are or broken up and used for hardcore. I also have a bag of smaller pieces of sandstone and pebbles from around the garden that could become hardcore.
