[MCU] [Far From Home] What was Mysterio's long-term plan?

Assuming he got away with it and everyone believed him to be a superhero — what then? Did he plan to make a lot of money? Also how did he fund his illusions and pay his team?

Mysterio says it more than once...the plan is to be "the next Iron Man". 

That is a very specific sort of goal.  Not just any superhero, but specifically Iron Man.  Why Iron Man?  Because (from the perspective of Team Mysterio, at least...) Iron Man never had to sacrifice anything to be a hero.  He's a regular guy with advanced technology that made him into a global celebrity.  He privatized world peace.  He negotiated with world leaders, he lived in a palace, his money and power were legendary.

With Tony gone, the world is going to be looking for the next billionaire-genius-playboy-philanthropist.  If somebody stepped up and took over the role as hero, and played their cards right, they could be set for life.  After all, Mysterio is from another dimension - no shame in letting a grateful world fund his operations, right?

The other motivation you have to remember is that the entire Team Mysterio hated Tony Stark.  Even if the project fails, or they don't manage to get rich...  If they can upstage Tony and make a Bigger, Better hero, it's a slap in the face to what he accomplished.  Prove that he was never anything without the suit, and make sure he's forgotten.
