If you shoot for 9' columns, you could cut the 20' rebar sticks in half, giving you 10' lengths. Then when you pour the footing, and while the concrete is just starting to set up, simply stick the rebar straight down, 1' into the wet concrete, sticking up 9' out of the footings. After the footings set, put the sonotubes over the lengths of rebar. Use a little timber at the top of the sonotubes to hold the vertical rebar in position when you pour in the concrete for the columns. Simple.
Putting a slab on top makes it VERY difficult. This requires massive formwork to hold the slab in place at the top of the columns. This is for professionals only.
It MAY be possible to cast a slab on the ground and lift it into place afterwards, but I don't see the point in going through that. Put a shipping container or a wooden deck on top, much easier.
