That will only work if the tower is on a standard or tilt base plate.  If 
its on a concrete base section or drive-in plate, you will have to go to the 
old temporary rope guy and gin pole method or hire a crane.  With the method 
you describe, you still need to "chock" the base to prevent it from kicking 
out.  Working close to power lines, as the original poster mentions, is a 
scary job with any method.
