Pros
Work from home.
Get as much work as you can manage.
Set your own pace.
Cons
Very difficult to make enough to justify your time. I have been working in training mode, and basically the "training" is them showing you an example and then pointing out what you do wrong while you attempt to work with a client. There is not much creative thinking aside from attempting to rephrase prior experience. It has taken almost a week with every client working a few hours a day, meaning you are paid around 13 pounds for almost 6 hours of work. Perhaps I am just really bad at it, but I have been writing for over ten years and have never felt so discouraged at a job.
