Hire a sign truck.
They are designed to lift light loads qite high!
The trucks are smaller and lighter that a crane.
The bottom line, less $$$$

  Since you will only be lifting a few hundred pounds, a light crane is all
  you need ...  the only thing you need is to be sure you have enough "reach".
  At WR1X, we put up a 90 foot tower using a 45 ton crane and lifted Rohn 45
  three sections at a time.   This beast was BIG and you probably don't want
  one on your lawn.

  When taking apart the old tower, you should probably have someone blast the
  joints with your favorite penetrating oil a day before.  Consider having a
  guy on the tower using a hand jack to pull/push the sections apart to avoid
  bending Z braces of the tower section.  It is difficult for the crane
  operator to know when he is pulling too hard.

  Be certain to make sure the sections of the new tower fit together well
  before the crane arrives .... they often get bent a bit in shipping, and it
  is a lot easier to fix them on the ground than on the tower.

  Renting a crane is a great way to go ... so much better than fooling with a
  gin pole!
