I'm a graphic designer, hustling for 12 years now. This part emphasizes that you've been working as a graphic designer for a significant period. Got a FORD 4X4, a Z1000 motorbike, 4 cribs, a cow shed, a repair shop gig, and 2 design joints." This part lists the possessions and businesses you have. "Got" is an informal way of saying "have," and "cribs" is slang for houses. "Cow shed" refers to a structure where cows are kept, typically on a farm. "Gig" is an informal term for a job or business opportunity, and "joints" here refers to places of business, in this case, design studios.
