I found a steel fabrication company about 30 miles from home and went
there with some drawings and measurements of what I needed to put in the
8x8 by 8 foot deep hole. They sold me the rebar I needed and the six or
so sections I needed in a "square", they bent for free. I went down with
a landscape trailer a couple days later and brought all of the rebar home.
