$1395 for a 20x20 carport, $675 shipping to Port of Hilo, total $2070.
Side effect: it's a "pre-engineered structure" and thus permit-exempt when installed on ag-zoned land (HRS 48-33).
Rough estimate for the homebrew version, assuming "greenhouse-style" construction (legs set in concrete) and the use of a pipe bender:
10 pieces 1 3/8 x 21' fence rail at $25/each = $250
7 pieces 20' roof at $100/each = $700
I would probably modify the design slightly and use wood purlins so that the roofing could be installed in its "conventional" orientation, with a ridge cap on top.
Done right, it would probably last 20 years.
