I have no prior professional/paying employment, but I have been personally recording off and on for around a year to a year and a half looking for the right jobs to surface and when I felt I was ready to jump into the voice over world. The one voice I have honed would be my "commercial/radio" voice. I have a deep and articulate way of speaking and that stems from my grandfather. His voice was the same and he showed me how to work with my voice since he had worked as a radio personality for years.
I have no prior professional training or education, but that hasn't stopped me before. I trained myself in digital graphic designing and I have made some money from that.

The most relevant additional skill that I can think of would be being able to pre-edit recordings to make them sound crisp and clean, as though I record in a professional studio. For examples of such, check out my Soundcloud here: https://soundcloud.com/morgan-martin-mrmojamamc.
