That brings up a question: What can you do to earn $50 in 24 hours? Unless you already have mturk the waiting period is days to weeks if you're not rejected. Fiverr/Upwork would all require a large amount of luck to make $50 in one day as communication with client and turn-around time could take 12-24 hours before even starting a small one hour project. CL might be the best way to make that money in that time period…
People Ready (aka Labor Ready). Be there early before they open, and if you're lucky (because I'm sure they're swamped these days) you'll get a full day's work. You get paid that evening.
I bring this up because people actually do call day labor companies for this all the time.
