There are not that many ways to make money fast either offline or online.
However online you do have a chance if you have something to sell.
In that case you should go right to eBay and post anything that you have for sale on the site.
Give yourself a one to three day auction if you want money fast.
However keep in mind that people don't always pay that fast once you have sold them something.
So there is always a risk that there will be a bit of a wait.
There are some sites online that will immediately buy articles from you if you write them.
Keep in mind that this is very small change but you will probably get paid quite fast.
These sites, like Helium and Constant Contact post writing jobs and you can often get cash within a day or two for writing for the site.
You could also make money quickly if you post a profile on Guru or Elance and then start bidding on jobs posted.
If you do this you have to bid quite low and only look for projects that don't pay that well.
You can work as a writer, designer, virtual assistant - there are many options for selling services on these sites.
Quite a few people make a living this way.
Yet another way to make money fast would be to enroll as an expert on one of the many advice sites online.
Two of the most popular are Kasamba and Keen.
Kasamba supplies a pop up chat that you can give advice on as any kind of expert.
Keen offers classic phone lines.
Both sites take hefty cuts of what you make but they are two sites known for being reliable when it comes to ways to make money fast.
