Yeah, I've done classes before, and would be willing to do them again. Just have to find the right time when we're not buried with work. The last class we had brought people from all over the country, and some from Holland. It was an awesome class, and a great success! Meguiar's and AutoGeek sponsored the class, and had products to provide for giveaways and door prizes, along with products and tools to use during the class. I can't thank them enough for what they sent. Must of been a couple of thousand $$$ worth of detailing supplies.
I've never charged for a class, only asked that people chip in for my expenses(lunch, renting chairs/tables, etc...). If theres enough interest I'd be willing to do another one for DFWStangers. But so far I've only had 1-3 people interested. Hardly enough to shut down my business for a day, if you know what I mean.
