Hardcore/stones/rubble available for free in Lower Clapton

I have just been sieving the soil in our garden ready for vegetable planting and have a load of rubble and stones. Not sure exactly how much is there and would estimate 15-20 fertilizer bags full. Perfect if you have a landscaping project. Happy to deliver locally but will need a hand putting it into fertilizer bags or something to transport it in (you will also need to supply the bags). Keen to find a home for it ASAP. Photo of half of the stones attached. Carl”
