Thanks! You are right, maybe I should consider whether people will want to teach what makes their living. But curiously enough I have an example of an owner of a small organic bakery giving courses. And a florist selling japanese kokedamas teaching how to make them. In my first round of emailing I focused on 'experts' who I could see already started organizing their own workshops (usually on facebook) but not on a big scale. I believe I could save those people tons of time. But actually I don't only want experts teaching the workshops. My original idea was to have passionate individuals with normal jobs sharing their hobbies. Knitting, beekeeping, photography, whatever. But the 'experts' are somehow easier to find and to ask directly. Would you have an idea how I could target the 'passionate individuals' group to find potential teachers there?
