Sankarea Episode 12

Wouldn't it be better if they just asked than Sankas some money so that they could do everything that a "Normal Girl" does, you know, for budget (admit it, it is easier if you/they have budget). That way, Chihiro will not just fulfill Rea's wish he'll also get to examine her more because she's moving a lot. It's probably not very wise, but it's better than just sitting there all day, making videos of her and just using present information about zombies as a guide right??!! Also if Rea or any of them contradicts about asking for help from Rea's father, can't they say something like, "I'm finding ways to stop her body from decaying" or " I am helping her" or something.
