I spent a few different weekends taking private lessons from Eugene Burger. Wasn't cheap. At all...but the information I gained was something that I really couldn't find in a DVD or even in a book. It's happening to you, and it's personal.
I have a pretty good idea what Eugene would ask for but then I've had a couple of teachers that are known for a flat $1,000.00+ a day rate and if travel were involved, more than a two day minimum was the norm. But we're talking about some seriously advanced classes.
To me $25.00 for anything more than a 15 minute teaser class isn't wise; you are creating a potential competitor within your own regional market. If it's a poor little rich kid, CHARGE MONEY in that they will not care about stepping on your toes a year or so down the road and take cash from your pocket; I've seen it happen far too many times.
Several people have argued that teaching someone the basics won't go over when they've be better off with a book of DVD. . . I find that appalling and rather myopic given that every art form requires the student to learn the fundamentals and in order to learn them properly you must have someone that knows those techniques that can teach them . . . making certain your form is correct. Many a major player, even when they were stars of the trade, paid big money to the Chavez School of Magic for many years, to learn these basics and become superior technicians. This same school took people from novice to pro for decades by the hands of Niel Foster, Dale Salwak, and Norm Nielsen to name a few, the the per lesson price wasn't cheap.
If you sit down with a student and book and walk through each move together, you help that student gain a far more rounded understanding of things; this is the same principle used in public schools and other learning institutions that's worked for more than a few hundred years now. But as part of that lesson you show them how to use that move; walk them through a handful of routines using one and then more and more moves and within a short period of time you challenge them to create their own routine combination using that foundation material. This is what brings about growth but it does something else that's rather important; it helps weed out those that just want to learn a trick. We serve no one when we just teach them "tricks" and I can assure you, this sort of impatient student have little to no respect for the craft.
A few of you here I've kind of pulled under wing and I'm not asking for anything from you. I took you on as a "student" (figuratively) because you show tenacity and initiative. This is what you need to consider when taking on a possible student; think like
Mr. Miyagi in how to help the prospect EARN and VALUE what you are sharing. When you can find the student that's willing to do whatever it takes to LEARN you and that student, will go much further in the relationship than money can buy.
My point is, if someone is going to take up your time it needs to be valuable to you. Money is one thing that makes it a thing of value but it is not always the driving force, sometimes it's not worth any sum of cash whatsoever.
