I spent my time working as a broadcast media specialist. This includes radio broadcasting, newscasting, news writing, news directing, and DJ (voice acting). For me doing such is my forte for years. I'm still open to learning more of course. I did a lot of voice-overs for radio commercials and even transcriptions for news.
No specific instructions for the buyer as long as the material is good and ready for the voice-overs I'm on it. I just have to constantly communicate with the buyer.
