Have a conversation

Go to a conference (here's how) and network as if you were "one of them. Then, have an entertaining, revealing conversation and videotape it. (You might, out of politeness, decide to obscure the face of the person you're talking to: it's the overall thing, not the particular person, that's really your target here.)

Finding a conference is easy. If you live in a city, look up the schedule of your downtown conference center. You can also search on "'trade show' chicago", for example, or you can go ask someone at the conference center for a schedule. Conferences also go on all the time at any hotel with a conference center, which is most of them. Explore!
