I know there are several methods to earn money online, but I like to know the fastest way you could utilize with $0 in hand.
Yes if you have skills you can make $$$$ in a week. Try at odesk or if you're good in designing try to design web templates like wordpress.
Clear out your junk and sell some stuff on ebay, you'd be surprised at how much you might get for it. If you have skills, freelancing is another good idea. You can always try listing a gig on Fiverr.com Not to pimp my own sig, but brokering is a very good way to raise good money in a short period of time. It's how I got started.
It really depends on your skills and your previous history. Lets say for example you are a web designer or a good write, you can't just come to digitalpoint as a new member and expect to get many job assignments without a free or very high discounted review or at the least some examples. If you are not good with digital stuff, then you may need to search on craigslist (if you live in the US) for gigs or temporary jobs or maybe permanent jobs. If you have some work experience and can prove it then you shouldn't have much trouble finding something. But on some cases you may need to make some sacrifices like accepting a lower rate if you need the money urgently.
There are many freelance websites were you can bid on projects. You should search for Data entry jobs.
CPA is the best way I found. As long as it allows email so you can utilize craigslist or similar sites.
I will try to sell my signature links for $85 for year. OR I will sell some links on high PR sites and blogs, so I get my share
