Ekka's right of course a crane is the way to go, a favourite method for me too, love working with cranes.
Presuming you meant how much for a crane with a reach of 35m? That would be a 120Ton since an all terrain 80T has only really useful reach of 24m. 120T crane is expensive (but great fun to work with!!

) You're right to be careful about your first crane job, perhaps if you could help out with another crew on one of their crane jobs? (I don't know your circumstances work wise) Not all crane companies are equal (see Ekka and Jim's post on the Queen palm removals) only experience will tell you which ones to go with.
If and when you do move into working with cranes a bit of advice....get the rep to come out to the job site and assess your work plan, use this time to suss out the crane company...how long has the rep worked for them...what tree experience do they have....who will be the crane operator...how long has he/she been working for them, and what tree experience. If the rep can't answer your questions to your satisfaction give them the flick.
As for the 2 tips see attachment..for me of course the safety aspect of having an escape route in case of emergency is critical, but the 2nd tip being attached to your front D's is far more comfortable than the side D's, it allows you to have a more comfortable position both working and resting...less fatigue=greater safety and efficiency.
