Also, it's highly unlikely that moving will be as expensive as $16,000 anyways. Perhaps $6,000-$7,000 for a small family of two?

Also, it is just not a good idea to borrow $15,000 on multiple credit cards at high interest rates when there is no guarantee that you will earn sufficient income to pay that money back in your new location.
It's easy to give out this kind of trash advice to other rich(ish) people on the internet. I wonder if you'd dare tell someone who was actually in the kind of situation you're describing that they ought to incur $15,000 in credit card debt and move to the middle of nowhere.
Even with non-terrible credit, you aren't going to get multiple credit cards with a total of $15,000 in credit line if you are food insecure; you might have gotten them first, maintained zero balance so that that money is all available for relocation, and then become food insecure, but that's a rather exceptional set of circumstances, not the norm.
