They're independent contractors. The pay is something to the effect of $15 an hour + drinks on the bar while they're there.
I don't personally know of any MCs who do that as their day job, and they're generally recruited (in my experience) through craigslist ads and/or "want to make some extra money" type ads on the side of the road.
