Chris,
I'm in the "commercial" communications business. We produce training videos, interactive CD Rom, corporate communications, meetings and events. For an overview, check out our website at
http://www.rainbowcommunications.com
I'm the head writer. I wrote the verbiage on the website as well as most of the scripts and copy for the printed materials you'll see there. You'll also hear my voice on some of our examples as I am also the in-house vocal talent. Unfortunately, they didn't see fit to put any of my "on-camera" or stage appearances on our demos. I'm also "cheap, last minute" on camera talent when necessary . . . "and other duties, as assigned."
PS If you click on the first example under video/film production, you can see an "updated" version of the fellow who acted as telent in our "'92 SVX Owner's Manual on Videotape."
