All the hitmen ever.
I'm not sure real hitmen, accessible to the common man, exist outside of video games and films. I'm sure gangs and organized crime have their own in-house goons they'd send to kill someone but I'm never, ever going to find a "legitimate" freelance guy who kills for cash.
Not in the US, certainly. In most of Asia you could probably find someone willing to kill a stranger for $100 without real difficulty or risk. Wait, no, I could. You they would assume were representing some sort of Candid Camera operation.

Straight. **** off and let me post. It's not true, it's all in good fun. Now go away.
