Look into become a Affiliate Marketer. There is a lot of crap out there, but if you go to the right places, some websites actually get you somewhere. This would take about 2 hours a day of dedication. In the beginning maybe more.
You can also think about learning Web Design or Web Programming. Take some courses, and become qualified in a certain area and work as a freelancer.
Or do your research and maybe open up a online shop selling a niche product or just sell in a certain area. Look into, selling on ebay. This is still rewarding if you know where to go.
The above is just 1% of what you can use to earn online. The best thing to do is get out there, make mistakes, learn from them and see what your most comfortable with. Worked for me
