This is actually a market where there are many real business models that work. Advertising is the most dominant one via job ads, and that could be a way to go.

Alternatively, I think people would pay for accurately telling them what they should do with their life that would provide them with the most fulfillment; and more if you're directly able to place them in that job/industry (similar to how a dating service could find you the person to marry).
