Broken paving slabs (Henley Green Coventry CV2)

I need to rebuild my raised gardens they have finally rotted and there is soil and plants all over. So I am in the need of any paving slabs large rocks or even breeze blocks to re build my gardens so I can enjoy without being in pain I suffer from disabilities so cannot reach ground level, I do not drive but would willingly pay petrol costs to the cv21df area. Thank you so much for reading. Tracy x
