"Do I need an agent?"

Those just jumping into doing voice overs may long for agent representation thinking it will lead to great jobs falling in their lap. Odds are, it won't. Which leads to the question, "Do I need a voice over agent to succeed in the competitive voice over field?" The rather vague answer is "It all depends." You say, "Depends on what?" It depends on what kind of voice over you are pursuing and what your goals are; where you want to go. There are many voice actors making a good living without an agent. They may be thriving in non union corporate narration or learning voice over. Or perhaps are in demand for audio book narration.  On the other hand, if you're looking to land a national TV commercial , you're more than likely going to need an agent. Why? Because capable agents can get you in the door for an audition and hopefully a sweet voice over gig.  Also, they have access to casting/audition notices early in the process.  They have connections.  But remember this: An agent can't land you the job. That's on you and your audition. There is no magic wand. Having an agent is no guarantee of future success in the VO industry. And getting an agent to bring you onboard can be very frustrating. They may already have a voice talent that sounds similar to you. They have a roster of voice talents they represent and handle. They don't need you at this time. Or,they're just not that impressed with your demo. And when you approach an agent and are lucky enough to present your demo for representation consideration, it's got to be good. Really good. Like the old saying goes, "You never get a second chance to make a first impression." I would say concentrate on your marketing and letting people know you're available and studio equipped at home. Don't get caught up on the fact that you don't have an agent. Remember, they're not magicians. Much of your success will depend on YOU.
