The quickest way to make money in my mind is to take one of two paths.
If you live in a low cost of living area, I would look to see if you can get a service job (retail, restaurant, etc). They will hire pretty quickly and you can get some money coming in (low hourly rate though it may be).
Alternatively, reach out to your network, of people you have worked with in the past decade and let them know you are looking for work. The phrase I like to use is "do you know anyone looking for an extra pair of hands". I suggest invoicing weekly to help with your cash flow, and aiming for small or midsize companies. This will be hit or miss, but if you throw the net wide enough you'll find someone who will want you to start contracting pretty quickly, because you are a known quantity. LinkedIn can be a great place to start building this list, depending on how up to date you have kept your network.
The second method takes more work and you'll have some risk, but should have a better hourly rate.
