Cool to see progress!
We can't do monolithic slabs here because of freeze/thaw. Not on a building. Do it a lot with pavilions and just outdoor slabs. We either do stem-wall, or similar. That said, when doing a pole building, we seldom use footers. Generally we put of the building, case the lower half in treated lumber and fill the floor into the area, no footer except at the door openings. (At door openings a footer is put in place, then the floor poured on top of it.) If the building isn't heated, the floor will float on the freeze. If heated, the underneath side stays thawed, so no issue. The building is supported on the posts that are set, so no worries. If stick built, like I said, stem-wall (poured foundation, then mason block up to the desired height) or sometimes poured walls depending on application.
You mentioned cost.... yeah, concrete work is expensive. We just built a 1 car garage for a lady late last fall. (Finished in December.) We had the foundation poured, wall poured to 18" or so, then floor poured. Garage was like 12'X24' and had a breezeway that attached it to the house that was maybe 5'X10'. I think the floor was 4". The company we sub'd leveled the area and dug the foundation, so they did all the base work. It was about $9,000 if I remember correctly, and they didn't do the driveway. Some of her family did that. We built the garage and breezeway. I think our part was about $7,000. So.... yeah. It's expensive.
