You can use a rope to steer it somewhat. I didn't clearly articulate what I meant. Primarily, steering is dictated by the face cut and a good hinge. Once the hinge breaks, then its possible to pull the tree to the side somewhat. With an open-facecut, say 90 degrees or more, a live tree with good hinge characteristics, which I'd say is most, when cut right, will be within feet of the ground before the hinge breaks.
Primarily, ropes are used to get the tree's center of gravity beyond the hinge in the direction of the lay, or as a backup in the case that its difficult to determine if the tree does or doesn't lean over its center of gravity toward the lay, and when people aren't both comfortable and confident in felling with wedges.
Again, I agree that expertise is part of what someone is paying for, and a person wouldn't charge for 5 minutes at say $100 per hour and get $8 or $9 for the job.
If you search cherry picker ( 2 words) and see Terence's post under homeowner help, you'll see the pictures, and see that its more of less just a spar with a few branches, previously storm damaged and pruned, I think.
