I built a freestanding 54' high vertical in Aruba which stayed up OK in the wind. (picture http://qrz.com/db/P40A )  The base was 3" diameter tube and it tapered to 1/2" at the top and I used a steel channel in concrete for the base using a plastic tube around it for an insulator. I could put it up myself using a bolt on the base as a hinge.  It was not that expensive to build.  To go 67' it would have to have bigger tubing at the base, maybe 4" diameter.

Thanks John

But very expensive. A universal tower, 50ft tall is about $ 959

But maybe need to spend more $$$ to have it ready, insulate the legs, add aluminum section on top, connections for coaxial, etc.

Maybe buying aluminum sections to build them and doing a support as you said will be cheaper
