You will get stuck with most of Palla's expenses every week until you get her making enough to cover it. Using the phone, just look for and keep assigning her jobs as they come available when her new bar (briefcase) starts filling.
As for Harmony, I think she is just a teaser for now. I dropped her alignment bar to 80, but her LP caps at 20. You can't do anything with her.
Yeah, my MC currently makes not even half that and I don't have any issue. It only amounted to about an extra loss of $250 for me each week, but it goes down as you get Palla better jobs.
