If you don’t already have a job, you can try your luck with a day labor agency in your area such as Labor Works or People Ready. Generally, these jobs are of the low-skill, low-pay variety — construction helper, mover, retail or warehouse work. Arrive early in the morning, and if you’re chosen for a job, you’ll work that same day and receive payment at the end of your shift.
Sell things to pedestrians. Entrepreneurial sorts sell things like cold drinks on hot days or hot nuts in winter. This method can be especially lucrative if you set up a spot near a sporting event, park, etc. You’ll need to have a small amount of money to invest in the product, but then you can sell it at a much higher return and make some quick cash.
You'll have to leave your house for this one, but hospitality consulting firms like Coyle rely on secret shoppers to evaluate their clients' services. Sign up to be an evaluator and you could get paid to receive spa treatments, dine at restaurants or stay at a hotel. There are lots of opportunities in other fields, too, ranging from entertainment (hello, amusement parks!) to automobiles. However, watch out for scams; check the MSPA for a list of legitimate mystery shopping companies. Earning potential: About $10 per hour
Get a bank loan. Banks and credit unions offer a wide variety of loan products. Some loans, like home equity loans, require you to offer your personal assets as collateral if you are not able to repay the loan. If you do not have a home or other assets, you may still be able to qualify for a personal loan, depending on your financial circumstances.
