Additionally, how do you convey to an employer without sounding like an asshole "Please, I need to be hired AND get paid at least 700$ before the end of this month"

You don't. Borrow the money from a friend or family, sell your TV (or other things you don't necessarily need right now). Talk to your land-lord about it, and try to get an extension temporarily. There are lots of things you can do.
If you've actually applied to more than 20 places and aren't getting hired, it's not your programming skills you need to be working on.
There is no shame from being denied a job, or starting from the bottom. We all had to at one point, and sometimes we are knocked down a few notches on our way back up, but there's nothing you can do but get back up and keep trying.
