I built my block foundation in 4 weekends. I would use a truck for footings and grout next time as mixing and wheel barrowing 300 60# bags of quikrete was brutal. Total cost was <4000, but that includes excavator rental and site prep. If you hire a truck i think it is difficult to handle that much without help and you are fucked if it sets too soon.

A concrete truck would not even make it down my road though... and many of the blocks were carried in small bundles by 4x4 truck. Building a road for heavy trucks would probably cost as much as the house.
