I've been on similar projects where the client is paying through the nose to a consultancy. I was being paid about £500 a day for my time, but I am sure they were charging the client much more.

I got flown out and put up at a hotel for a week for a PR emergency (it was the 5th anniversary of a merger no one cared about but the new CEO wanted to do something about it) ultimately to make a wordpress site. Everything on my expense report got marked up some percent and passed off to the hiring company. I maybe got a little bonus for the whole thing, so not terrible? Not great. I read Bullshit Jobs a little bit later and it hit a little close to home.
