First of all, I would like to discuss the differences between an agent and a manager. While an agent takes a commission (a portion of what you earn) a manager is paid a flat rate, and is more there to help you, as opposed to an agent who is booking you performance opportunities. While eventually having an agent is necessary if your career takes off, most professional singers would suggest that instead of searching for an agent, spend your time and money auditioning and finding jobs, and eventually a good agent will come to you. A manager, on the other hand, can be very helpful in terms of giving you a good name. I suggest working with your voice teacher to find a manager that could be right for you, although again, it is often suggested that one wait to find a manager until his or her career has some substance. Don’t worry about this just yet!
