I can't speak for the list, but I think it's a safe bet that very few, 
if anyone, here has constructed their own tower from scratch as you 
propose. Most of us use engineered towers. If you want any kind of 
permanence and to also avoid liability for a structural failure that 
could injure someone or damage property, you should probably go that 
route. Often used towers in good condition can be had at a very good 
price, so to save money you could start there. If you have no knowledge 
of tower installations or methods, you need to hire someone to do the 
engineering and work.
