Concrete base for shed help

[Surfncanoe]

Hi all
I am shortly going to be taking delivery of a 16 x10 shed. I want to make a concrete foundation..could anyone advise whether it may be cheaper to purchase ready mixed concrete, rather than sand and cement etc and mix myself. Many thanks

Personally I'd get a good shuttering in place, and then call those people who will mix and barrow on site....you pay for what you use and they'll help with the tamping down!

There are factors to consider before deciding. Access being a large contributor.
Access?
Quantity?
Logistics?
Working time?

As it is only 3 tonne of ballast and aboot 20 x 25kg bags of dust we would likely hand mix unless the waggon can shoot the muck straight into the shutter.
