Looking for the supply of 20 tonnes of white stone

Hi everyone ... brand new to the forum ... so will do my best not to break any rules or offend. Posted this query on another forum however grateful for any replies that the community can provide.

We have recently bought a property on the outskirts of Villanueva de Algaidas and fairly urgently need to source 20 tonnes of white stone in order to suppress horrendous weed growth at the side of the house. I have already sprayed it and intend to place a membrane on the ground prior to the stones distribution.

I have made enquiries at the large builders merchants down in Malaga however the transportation costs are pretty astronomical given the distance involved. I have also sent email enquiries to a couple of suppliers that I found on the internet however again too far away from our location.

Our preference would be the larger natural white stone product (20-30mm size) as opposed to the smaller white gravel product. I have tried searching for 'stones' in the forum however no joy (although it could well be operator error).

Extremely grateful for any replies.

Many thanks .... w33lpm
