My experience is minimal, but I have done paid-for work. My voice adorns the answering machines of several of my friends.
I have a day job that most fourteen-year-old boys would kill for (I "play with computers all day long", according to my wife), but I love to do voice-work, so it is a passion for me.
I am at home with technical, medical and scientific terminology, and am good with foreign words and names, striving for native pronunciation wherever possible.
I have also been told that I have exceptional writing, spelling and proofreading skills, so I can help with writing and editing scripts if you wish.
Bachelor's Degree in Applied Sciences (Computing & Electronics, with some undergraduate Biology, Chemistry and Biochemistry)
My microphone of choice is the Audio Technica AT2020, and I have several computers that I can use with it. I also have access to a soundproof studio if background noise is an issue.
I would rather not be paid than deliver shoddy work. If you don't like what you hear, I will not accept your money.
The nature of my job means that I can take time off for large projects when necessary.
