concrete slabs and sand (Costessey NR8)

We have to take up an outdoor wooden floor which is rotting and need slabs to go in its place please. Any amount is considered as it's a large area, but I can't drive too far from NR8 - NR1, as fuel is limited financially too. Also if anyone has some sand left over from a project, that would help enormously to bed the slabs down. Thank you so much.
