Obviously there are some great suggestions here. Not knowing much about this line of work, and probably having no business answering, I have a recommendation to think about.
You could upload videos to YouTube or another video upload site. Use other methods too of course, but record your voice doing what you do best and upload it. Get your voice out there and get an audience. The more people hear you, the better your chances of catching the attention of the right person. If you use material free of copyright obligations, you could even monetize it.
