Hello, I am very interested in this project. For me, 2 - 3 articles per week would be great as I am not sure that I can commit to more. I am also new to WordPress so I think this could be a great oportunity for me, to gain some experience with it. In the past, I have written articles on nutrition, health, physical conditioning so, if needed I would gladly do a test article for you on a given topic, before any further employment details are discussed.
Good day!
