More just to mean that he'll get paid ridiculously well. Probably a bad choice of words. I didn't mean to give that impression.
What the PA hire is looking at here is a few years of $30-50,000 (if he'll even get that) followed by an immediate bump to the low six figures. Over the course of his career he'll steadily work his way to the high six figures.
This is pretty much guaranteed, although it's not stated anywhere in any contract or in the ad. Professionals in entertainment typically make an order of magnitude more than their contemporaries, after they get in and are vetted, join the trade association, etc.
You just have to get in. This involves getting a well-known production to take a chance on you. A lot of people bum around entertainment for ten-fifteen years before they catch their break. That break typically comes in the form of a very part-time gig on a huge production. You might get some face time with a big name.
That's when everything changes. Overnight, your marketability goes up tenfold. You keep working with bigger and bigger names and before you know it, you're rolling in cash and bennies.
This looks like a horrible job ad when you look at it from our perspective, but what it really offers is a short-cut. You can jump out of the IT industry and the generally shitty 'opportunities' it offers and hop immediately on the fast-track to success. You don't have to bum around with the hangers-on for years, you can get your foot in the door immediately. This is a truly Edison-type opportunity, one that comes dressed in overalls and looks like work.
Entertainment types don't typically hire outside the industry. Outsiders just don't understand it, can't quite grasp their priorities. That's why they chew through so many young people and burn them out, because they can't get outside professionals to work they way they need to.
PA is willing to, and you'd be a fool not to jump on it.
