property renovation

I have bought a large property in Brittany which needs renovation. I would like to use Local “Rose Granite” but cannot find a supplier.
I would use it for window sills, kitchen worktops, fireplace hearths etc.
Does anyone know if it would be practical to buy a block and cut it myself?. The cost of Custom made stuff is astronomical. Does anyone have any experience? I suppose I’d need a granite saw and a planer. How are these sink units made?
Any help would be appriciated.
