A question I hear multiple times, daily, sometimes hourly.
But is it the right question to be asking?
It's really important to take a step back and think first about what it is you want from your relationship with an agent; asides from the obvious "lots of jobs".
Is is marketing support and booking you appointments? Do you feel swamped when it comes to organising a production? Are you looking for a creative mentor? Or do you feel in a weaker position when quoting to clients?
When you've asked your self those questions first, then it's time to think about how you find your perfect Agent.
