You need some cash. Working, donating plasma, and begging are all out of the question. However, you do have access to an excavator and a van of some sorts that you're able to cut a hole in the top of it. Also I'm assuming there's a 2nd vehicle with a trailer to carry that digger. Seems like a lot of work to basically guarantee you're going to get caught.
Sell the van? Sell the excavator?
Now this van will never be driven again. Forced an ATM through the top of it and smashed down, that suspension is SHOT. Plus it has been filmed at the scene of a crime.
Step two is now to get all the cash out. I'd imagine that its not as easy as it sounds. People tend to keep their cash locked up pretty good.
Step three is clean up after yourself, aka get rid of the van, and the ATM and put the digger back. How long do they think they had to get away. Its probably a good idea to be able to leave the scene of a crime as fast as possible. What a bunch of morons.
