I thought of listing some methods of getting quick cash. Maybe it will help somebody. The order is random:

1. Get a quick loan
Now there are a lot of loan providers, that can help you get a loan in 24h, 1h, instant, minus 1 hour, etc. Go there, apply for a loan and you get served

2. Rob someone
This is a quick way to get quick cash. But you have big chances to make a quick visit to state prison. So is not very wise

3. Go hire yourself.
The problem here is that you will not the cash quicker then 1 week/month.

4. Ask a friend to give you the cash
Once a very smart man said that the value of every person is the amount of money he can gather at 1 am calling his friends. So, the idea is to have good friends or family, so they can give the cash quick

5. Sell something
Yep. But first you need something to sell. Jewels, real estate, a car, stocks, bonds, something with resale value. Most of the stuff we buy have almost zero resale value (clothes, food, electronics, white goods, etc)

6. Make a quick business.
Basically is the above point. Post an ad on craigslist, saying you sell something, you sell and repeat the process. Make sure that you have something standardized that will sell quickly, otherwise you will be stuck with the merchandise

7. Gamble
Well, this is more a quick loosing money solution and earning it. At least try something you have 50%-50% chances. My suggestion is, if you really need quick cash, DON’t gamble. Otherwise there are big chances that you will need MORE cash

Good luck
