Hoppy, how large is the pile? If it's a large amount, well, if it was enough to do your extn, try a local stonemason, or if it's smaller, someone would use in a garden etc. I would try DoneDeal.ie or one of those sites, can't really help you with pricing it though, sorry, maybe call one of the natural stone suppliers Manor Stone near Abbeyleix is one and ask them how much per tonne if you wanted to buy either of these. We got our house stoned but the stonemason supplied all the stone so I don't exactly know how much it cost
