Are there any websites where i can sell my articles??

The only place I can think of is Associated Content. They pay by doing performance pay, which is 1.50$ per 1000 views and sometimes, if they love the article, you can submit it for an Upfront Payment which ranges anywhere from 1$ to 15$. I have their button on my profile if you want to check them out. Other than that, I can't really think of anywhere else that does Upfront Payment.
