That's basically how I did it, too. Teaching martial arts classes 3 to 5 times a week, for 3 hours a night (though that was many years and many beers ago). My coworkers remark on how well I speak in public, and while I get that from their perspective it's a scary thing, to me it's just another job. If you're in a reasonably sized city, there are probably dozens of tech meetups looking for content. Just start hanging out and you'll start seeing opportunities to talk. Take them. Also, when you're just starting out, stick to topics you know inside out. Only write enough notes to remind yourself of what you want to talk about. And then just talk to everyone. Don't make it a "presentation". Too much detail and you might get worried about sticking to the material. Just wing it.
