Associated Content (http://www.associatedcontent.com/) is the place for you. You sign up to be a writer and then you can submit videos, reviews, articles on nearly any subject. They pay you an upfront payment usually between $4-$10. But the great thing is that they also pay you every month on a per click basis. So say someone looks at an article you wrote, you get paid. This continues as long as you have an active account with Associated content. So you make money every month on past work you have done. Not a bad deal if you ask me. Granted it may not be much money until you have more articles on the site, but still a little extra cash every month isn't something to complain about.
This is a site I use often. I teach scrapbooking classes online and at local scrapbooking stores, so I often will take my lessons, edit them a bit to be more like tutorials or how to guides and post them with associated content. It's a great way to make a little extra money off of something you are already doing. If you are a stay at home mom who has done some research on your childs certain behaviors write up a little article on what you learned and make some extra cash. This works for a lot of people.
