Save yourself money and build a concrete shed slab / foundation for your shed project yourself. This just takes a bit of organization and some labor. If your shed slab / foundation requires more than 1 cubic meter, it may be worth hiring a small pump truck to just pump in the concrete for you. This project cost me about $300 and was about half a cubic meter. The pump truck would have been more than double this price with a 1 cubic meter minimum.
