Janet Ault. The Voice of Choice.®
If you are a voice over actor with no knack for business marketing, you are going to have a difficult time succeeding in the voice over industry. No matter how many companies need someone to act as a voice over narrator or do some voice over commercials, chances are another voice over talent will take those opportunities because the right people don't know you exist.
The business aspect of voice acting must be taken into consideration if you are to be successful in this field. Janet Ault, a freelance voice over talent who started some 10 years ago, established herself as "The Voice of Choice™" because she successfully marketed herself and her services. And you can do the same.
Another benefit in talking to people and leaving a good impression on them is that they might know someone who requires the services of a voice over actor. Even if the person you are talking to does not need your services, it is very possible that they know someone who does and can hand your card off to others.
By creating your own brand, you make yourself distinct from your competition. Making yourself a tad different from the others but still an expert in your line of voice acting will help drive the customers to you.
If you have the cash to spare, getting a PR firm to represent you and your brand is always a good move. An excellent PR firm can get you the exposure that advertising cannot provide. A PR company helps you concentrate on your business while helping you maintain a positive image.
