Every place I have ever worked including United Airlines as a Flight Attendant, people always make comments to me that I should do voice overs. Give me a call and I will allow you to conduct a Free interview. Though my time is valuable, I am willing to use a portion of my time to show you the skill.
Since Junior High, I have always been involved in some sort of school announcements over the pa system. I was also my High School's graduating class speaker. I have represented many companies in my years including BellSouth as a service representative. Even my customers at the time made comments like "You should really try voice acting".
I have been put in situations on the job in a management capacity where a problem arises and there was no real solution. After I speak with the person who has the problem, they kind of tell me that they are comforted just by the voice even if they did'nt get the initial problem fixed.
