For me it all started with my blog. Today, you can check out my information on my about me page, here on Hubpages.
I started a blog, but I wanted to do more writing wise, so I did some research, and I found Helium, then Triond, and finally Hubpages. Before I invested hours on these websites, I also invested some time on Bidding sites such as freelancejobs.com and problogger. Needless to say, I found incredible clients, but with the pay being so-so, I decided to stick with my own blogs, and the websites listed above. Soon after, I began to catch the attention of a few clients, and started doing guest blogging jobs that had a nice payout. Soon after, I had more than one high paying clients, and with my portfolio on these websites, I started to earn a descent amount of residual income.
It wasn't easy, but it has been a great learning experience!
All the best!
