If you want to make some money writing, here's a site that I see gets very little mention: Textbroker.com. (no affiliate link whatsoever)
I used to write for Textbroker and was very happy. They pay a fixed rate per word. Their pay rate goes according to writing ability. Starts at Level 2 which gets paid .7 cents per word, level 3 gets about 1.0 cents per word, level 4 gets 1.4 cents and level 5 gets .5 cents per word.
When you sign up, you'll need to submit a small writing sample. They'll give you a star rating; the average is a 3. They continually re-evaluate your rating and will upgrade you if they think you deserve more.
Textbroker pays a lot of attention to your grammar, especially comma usage. They pay about every two weeks (the 5th and the 15th). If I'm not mistaken, I think you need to be from the US to write there, (but don't take my word for it).
So if you're thinking about offering your services as a writer, consider this option. Just google "textbroker review" or something like that and see if it's for you.
Hope this information helps somebody!
