Marketing yourself as a new (or seasoned) voice-over artist takes time, trials & errors to find a balance that works for you. I say, "that works for you," because different strategies just work naturally for different personalities. Regardless of your personality, working freelance in any industry requires you to be more confident about your services, rates, and qualifications than working in Corporate America. This is obviously because you have no one (i.e., company) to vouch for you! You are your own manager, CEO, employee, and spokesperson -- all rolled into one!
In the beginning, marketing yourself to get voice-over jobs tends to make people feel uncomfortable because you feel like you're asking people for money. This is a common feeling when you are just starting out as a voice-over actor, so learn to be confident in your product! Remember that you have taken your voice-over courses, you have listened to our Marketing TIps CDs, and you have put in the hours of practice to become a professional voice actor. Not to mention, you have professionally recorded and mastered demos.
Hopefully you prepared your social media sites, website, and business cards in anticipation of hitting the ground running once you get your demos back from us. Tell your family and friends that you are looking for voice-over work. Most likely, you already know someone who could benefit from your voice-over work. Make sure you always carry your voice-over business cards on you. You probably don't like someone else "selling" you something, so be mindful of how you come off to people.
The trick is to be able to tell people what you do, how they can benefit from your services, and where they can go to listen to your demos and get in touch with you. Keep it short, and remember that certain qualities just don't sell, no matter what your style is: desperation, insecurity, and the over-sell.
Find a balance that works for you, and be patient with yourself!
