These gin poles are probably special order or custom made and will be
very expensive. If they are going to support 800# 20' sections they need
to be engineered to handle about twice that.
The gin pole is one of the most vulnerable and critical components used
during tower installation when done section by section. It's probably
why you only find relatively small ones advertized.
That being the case they require engineering at least to the same extent
as the original tower. Probably more as they have to support off center
Normally, climbing these monsters (although at 20" between legs they are
little fellers) is done on the outside with proper safety equipment
which also takes training.
This appears to be a job for a professional or construction crew as
something this massive is not a place to learn without expert
You've ruled out the ability to get a crane on sight. (Expensive but the
cheapest of your options) so were it me (and it's not) I'd be looking at
or talking to construction outfits, or professional climbers.

foot /tower/ guyed structure and a 100 foot rotating mast."
The photo shows the two towers mounted side by side with enough
clearance for the 100 foot rotating mast (tower sections) so they are
After looking at the photos I'd say this is a major, construction
project. I did not find the address for the photo of your tower sections.
Climbing and particularly erecting heavy towers is dangerous even for
those who do it as a profession.
Safety is paramount!
