The 15-year-old actor is off to a strong start in the family business after landing a recurring role on the Nickelodeon series, "Side Hustle." According to his minors contract, obtained by TMZ, Isaiah is banking $15k per episode in the first season alone.

Looks like season one has 10 episodes ... which should net him a cool $150k. And, get this ... he'll see significant increases per episode if the show's a hit and gets picked up for new seasons ... he could earn nearly $20k an episode by season 6.

This isn't Isaiah's first role in Hollywood. He appeared as himself in his pops' short-lived reality show "The Family Crews" a little over 10 years ago. He's probably used to the cameras ... what with his father being a huge Hollywood star and all.
