Seems to me there is a potentially interesting discussion here and I probably side with the idea that most qualified pool instructors do not charge enough. Here is why.
When I worked as a psychologist I expected to make $150.00 per hour. People do not often realize it but a 50 minute hour includes the time for the professional to organize their notes and do some planning for the next session. In reality an hour of work requires more like two hours with a new case and 1.5 hours with an “older” case.
Given this expected hourly rate I would also discount my rate for lengthy sessions for a corporate client because there was not as much down time between clients. If I usually made $1,200 for an eight hour day then I expected $800.00 plus expenses for an “all day” corporate client.
When offering workshops I would decide upon the minimum number of attendees and then spread the cost over the expected group. An eight hour workshop with ten people would cost each person $80.00. For an expected class of 20 it would be $40.00 per person. Additional expenses such as room rental, food, and equipment is then added into the cost of the day. In other words, the attendees paid all expenses as part of the tuition and the actual tuition might be $100.00 per person for an eight hour session.
Individual sessions are at the standard $150.00 per hour because, depending on the complexity of the case I usually put in more time than one hour given my own needs to structure a program for that person. In addition, most professionals provide some services pro bono (for free) to clients of their choosing and there is a need to have a target yearly income to pay one’s expenses and meet normal obligations.
There are times when one’s expertise is in demand. There were workshops I was not inclined to conduct but was persuaded by a corporate client to conduct through a financial inducement. That is, my fees doubled and I was pleased to travel some distance and conduct a workshop and consulting contract for a group who desired my services.
With experience and the development of one’s abilities fees increase. Today my fees would be substantially higher than they were ten years ago. In most professions one has an expected hourly rate and all services are based on these “usual and customary” fees. The insurance industry and the federal government may deny payment when one exceeds their “usual and customary” rates.
It is also customary to have set fees for specific tasks such as a standard psycho-neurological screening or a vocational assessment battery. While these are not fixed by law, the insurance groups and state and local governments are able to determine one’s usual and customary rates by one’s prior billings and they often set a fee that they will not exceed for some particular service.
While pool instructors are not “licensed medical providers” it is worth knowing how other professionals operate in the construction and operation of a service. The bottom line is that one should have an expected standard hourly rate. All services, with some exceptions, are based on the usual rate.
In my experience giving and attending professional workshops those who charge excessive fees because of their notoriety are not worth the money. They usually are no better than the average professional and often are not as knowledgeable or they only provide the outline for their prior publications. When they are a “famous” person I usually buy the book and save my money for other things. If they are famous and have not written a book then they are usually no better than the average professional.
BTW individual clients usually do not ask but most professionals are willing to tell you their rates. They are not that difficult to determine if someone wants to know. When someone would ask why I charged "so much" I can always show them my credentials, the time it took to earn them, the places that have used my services and most any other public information they might desire. The bottom line was always, when it comes to professional services you get what you pay for. A friend who was an attorney had a sign behind his desk that said, "You do not pay me for the hours I work, you pay me for what I know how to do."
There is an old joke about a fellow who took his car to a mechanic. The mechanic listened, took a mallet, tapped the car. The customer was amazed at a $100.00 bill and asked to have it itemized. Hitting car, $.50. Knowing where to hit car, $99.50.
