Adelaide Concrete Co. at $68,900 is the best overall value.

Southern Slabs is $7,500 cheaper on paper but excludes cut and fill and pump hire, both of which are required on this site.

Adelaide Concrete Co. is the only fully scoped quote — cut and fill and pump hire are priced, not excluded.
Adjusted for the excluded items, Southern Slabs lands between $73,500 and $76,000, above the recommended quote.
14-day lead time is the only option that holds the current slab pour date.
GST position is stated clearly; Southern Slabs does not state a GST position and needs clarification.
