I need to figure out money fast while I wait two weeks for a paycheck

I have a job but due to the nature of scheduling and onboarding in security I miscalculated how long it would take before my first shift.

As a result I am homeless (in sf) starting today and am additionally like 300 in overdraft. I'm trying to take gigs but it takes a while to approve, I'm trying to donate plasma hopefully, but aside from that I have no idea where to look when it comes to grinding money. Any tips
