If it is a 'Business' that you are looking online and not a 'job' then there are many options available. But Internet Affiliate Marketing is the most popular.
There should be some area / domain where one should have experience either working on or pursuing it as a passion / vocation. Once we have passion/affinity towards something, it is natural that we will want to share it to others. That is where Affiliate Marketing helps a great deal (as one of the member also says).
Remember, business takes time to build it - quite some time (may be 2 to 5 years, depending on the person concerned). There are many people are willing to put in a dozen or even dozens of years working as an employee to help others' businesses grow and thrive, but don't dedicate even a fraction of the time to build a Business that they can call their own.
