Quite some time ago, Jason Rose of Meguiar's and I hosted two, one-day training seminars. However, our situation was quite a bit different than Dave's. Our primary goal was to teach proper sanding and polishing techniques. We were actually attending the CES Show in Las Vegas, and had just wrapped a three hour training class at the local Meguiar's store. We got to chatting and thought, "Wouldn't it be GREAT to take a group of guys that truly want to learn sanding and polishing, and pack as much as we can into a one-day gig?" Our second goal was to do so using Meguiar's and Mirka products, for obvious reasons. At that time, Meguiar's and Mirka had combined forces to offer a kit sanding and polishing system consisting of a mix of their goods. Our third goal was to be efficient in our teaching because we would only have one day. We decided that the student to instructor ratio had to be low so we could be thorough. We aimed for 4:1 to 5:1 ratio. Our fourth goal was to host it somewhere appealing. We chose a couple of different car museums. I had a fifth goal, which was to turn a profit, and out of all of the goals, this was the hardest one to set and achieve. For these classes, I charged $500 per student, but included a kit worth over $500 retail. I made a fair profit on the goods. Out of that money, I had to pay for travel costs, food costs, demo product costs, and any other goods needed to host the class. In the end, I certainly did not come out of the class thinking, "I made a killing!", because in no way was that the case. I was able to make a few extra bucks in follow-up sales. In fact, had we not used Meguiar's and Mirka reps to teach the class, there would simply be no way to teach the class and pay all the instructors a respectable amount. Since I was supporting them through the purchase of goods, they were able to support me in hosting the class. The best part of the classes for me? I met some great people, I worked with high caliber instructors, and I was able to share some hard earned knowledge with some VERY appreciative guys. This is the point: What is your goal in teaching this class? If the goal is to TEACH because you wish to share knowledge and appreciate how much it would have helped you if you had access to similar knowledge early on in your detailing career, then charge accordingly. If the goal is to equal or rival what you typically earn doing something else with your time, charge accordingly. If the goal is to teach oodles of guys asking you for advice and you are tired of chatting on the phone or sending e-mails with no financial gain, charge accordingly. If the goal is to teach guys that are telling you, "Teach me, man... I'll pay!", then charge accordingly. My advice? Start at the point of what you might make in a typical day. Consider what you will need to make in order to cover your costs (food, product, whatever), and add your day of profit. It does not matter if you teach one guy or ten- that cost is easy to determine. With all the attention this thread has received, I think a group of guys would be willing to attend. They will learn from you, but they may also give you advice on teaching your next class. If I was looking to attend a class given by any particular chap, I'd immediately want to know what the class would cover, how long would the class be, and how many students would be attending. I could then better gauge the value. Once you get a class or two under your belt, there's a very high likelihood that you will know how much to charge in the long run. If you feel that teaching is more difficult and thus requires more profit than if you'd simply booked a detail for the day, charge more. If guys keep leaving saying, "Man- I would have paid two grand for this class- what a deal at only $200!", charge more. I think you are going to find that unless you are teaching only one or two guys at a time, you may need another instructor or two to run the class efficiently. You and Bob Willis could do it- but of course, more money would have to change hands so Bob could pocket some dough, too. Good luck.
