Teach a class through the continuing education department at a community college. Most programs will consider just about any topic if they think people will sign up. Sometimes these are single evening events, or can be extended courses that go on for weeks or months. . . . Plus, you’ll get paid for your time (usually based on a percentage of the registration fees).
There’s so much to gain from honing your presentation skills, it’s a shame not to give it a shot. You’ll feel great after a presentation well done. You’ll be able to reach people with your message more effectively than possible one-one-one or remotely. Done right, this can produce an additional revenue stream for your business (not to mention super opportunities for getting in front of prospects).
