In my opinion, tutors only work if both sides have patience, and if both sides are willing to learn. (Yes, even the tutor learns from the student.)
...and most good players nowadays, either have amazingly swollen egos, or they just can't be arsed.
And, as SlipAnc said, you just have to play and learn. Everyone's tutoring you, and you're being tutored by everyone, seeing as you have their techniques in display, by simple analysis of a replay. Of course, you can't learn ways of thinking, so you have to develop your own.
So, I find this idea simply dumb.
