Concrete footings for retaining wall

I'm after a quote to supply concrete for a retaining wall job on my own property. It will involve pouring a footing plus core-filling the block wall once it goes up. I'm happy to build the footing form work myself but I need to determine if it is cheaper for me to mix the concrete myself or bring in a truck. Footing dimensions as follows: Footing length: 14 m, width: 1.5 m, depth: .3m ~ 6.5 m3 Concrete specification: Minimum 25 mPa, 20 mm aggregate and slump of 80 – 100 mm Core filled block wall: Wall length: 14 m, Height: 1.7 m, Internal width: .15m ~ 3.5 m3 Not fussed on the concrete provided for the fill – whatever the suggested minimum specification is for this application. Also, there are no issues with access to the site. Cheers
