Well, I think it most likely that the actual work that has to be done on Mars would be done by the people there for free, because if they don't do it, they'll die...
Even in the longer run, I think it implausible that anybody on Mars would be doing anything at all that people on Earth would be interested in, once the initial excitement has worn off. And I think it more implausible yet that the Earth people will be interested in paying for it! Transporting physical materials would be impractical, even if you were prepared for the gargantuan expense, and while you could have some kind of remote working outpost, it's unclear how much use this would be to anybody. It's hard enough when people are only the other side of the world! - it's not going to be any easier if they're 50,000,000km away, with no phone connection, no postal service, and a ping time of at least 5 minutes.
As always, events may yet prove me wrong... but I don't expect them to.
