If you live in Los Angeles it's hard not to meet producers and celebrities. Waiters and limo drivers can't avoid meeting them. If you have the chutzpa to approach them ("hi, I'm Derek and I have a great kids-targeted franchise...") they'll smile at you and take your card (only to throw it out right away).
His house (where the videos were shot) seems to be in a suburb in the Valley (or maybe San Bernardino?). During the early 2000s you could get those for peanuts. Even after the 2008 they are still very affordable.
Derek seems to have taken an online branding course. The whole repeating ad-nauseam "Cool Cat loves you!" it's the kind of stuff they teach you at those.
