Marcel Irnie is an amateur racer from Kelowna, British Columbia, Canada who excels at self-promotion. This guy could give lessons on how to properly support your sponsors. His videos are better produced than the Canadian National racing stuff, or at least more interesting, and done on a shoestring budget.
He's also bought a couple of my shots for his site, so maybe I'm biased
