For what it's worth, the term "hustler" is used pretty frequently as a colloquialism for pro-actively selling in a range of industries. I've heard it used in reference to musicians, writers, actors and artists. In the Ricky Gervais series "Extras" in the episode with Patrick Stewart when Ricky accosts him to look through his script Patrick says "I know I know, you're hustling". There's also the popularisation of the term in the hip-hop culture (gotta hustle y'all, we gotta hustle) where the term represents achieving despite extreme adversity.
