I get paid for writing all the time. I got started bidding jobs as a content writer on rentacoder.com almost a decade ago and, once I built a name for myself and people started referring others to me, I have always been able to find paying clients.
It doesn't always pay as good as a regular job. It's mostly feast or famine. Some weeks you can clear several hundred dollars and other times, you can go a few weeks with almost nothing. If you decide to go into writing as your regular line of work, get some regular customers or have a back up plan.
If you need help getting started or need ideas on finding the work, just drop me a message and I will be happy to help.
