Like he said, contact the company who is going to install it. Then get a time schedule and hire a crane. Let the company installing it know this is your intention.
My good friend owns a crane company and he charges about $400 to do this , in about 2 hrs. He also does tree work and other things. Look for a company who has a good reputation for being on time. Also remember that weather is a factor , high winds and such also.
Save a buck, good luck.
