There are many things you can do to make money online as a worker like administrative support, business specialist, customer service or call center, data entry, telemarketing, web development or design and writing. You can try odesk, freelancer.com or elance. However, you can only make at least $0.50-$1.00 or more per hour in a real job.
You can also make money if you develop your own business online but you need more time in this kind of business. There are also some investment needed for you to make your own company. I do not advice you to invest in any business online because you can just do some writing or blog and use any affiliate programs you like to make money for free. All you have to do to make money using your website is online advertising.
