Most of my experience is with copy that is 30-45 minutes in length. As demonstrated in my samples, however, I am comfortable at any length of copy from 15-30 seconds to full books. And I have a technical background so I am equally comfortable with complex text or generic consumer-focused ads.
Have undergone professional training.
I have my own studio and am capable of delivering files via ipDTL. I also have access to a full recording studio that enables me to produce finished recordings including music.
I write and produce music and can add those talents to my voiceover work.
