You can just write an article and submit it at ezinearticles.com. They would review it first before it gets published same with other article directories so you don't have to show that you already have published something.
There are sites that do pay for your articles like bukisa and associated content but I think for the latter you need to be based in the US to earn money from your articles.

When you say you have to submit an article to show that you are a writer, do you mean that you need to show that you already have something published, or just that you need to demonstrate the quality of your writing? I've never attempted to have anything published, but I'm a writer nonetheless. I could absolutely write up some articles on dreads; I'd love to share this site and see more beautiful, natural dreads in the world.
