I sing (traditional folk songs) and accompany myself on guitar. I'm an experienced artist (on a local level), and i'm just starting to be known in my city. I've had three local managers and one agent approach me for representation. I perform at schools, city events and other venues to get exposure, etc. When does an artist need a manager or agent, and do any of you (who perform full-time or semi-fulltime) handle your own booking, publicity, finances, etc?
