Hi,
I'm a professional writer with over 6 years of experience, and I have written for many high-profile websites. I have a passion for sports as well, so that will help me write amazing content for you as well. As far as the creation of topics is concerned, I assure you that I stay updated with most sports, so I'd always have something great to write on.
And yes, I can write one article of about 300-500 words daily.
However, if you decide to hire me, I'd prefer a flat pay rate per article. Usually, it takes me a few hours to write a compelling piece that is great in quality and well-researched, hence, a flat rate of $18 would be better for you as the employee as well.
We can discuss further details in chat if you wish.
Regards,
