There's an auto dealer in my town who has a 1998 Mercury for five grand. Bet if I offer him $4,500 cash without putting him through the credit paperwork, the car can be mine today. Oh, but then there's that pesky insurance bullshit again...
My younger sister totally rewired her entire house after completing the training. Licensing depends on what state you're in. Some states require more credentials and some require considerably less.

By the way, there's no magma come loudly... or didn't you get that yet?
