Write an information security post (weekly)

I am looking for somebody who could write a security article every week. We are developing a platform for pentesters and we need these articles to attract them to our site.
The articles could be about anything that is computer/network security related: recent hacks, best practices, explain typical vulnerabilities, etc.
The articles don't need to be long necessarily, but must be unique and offer something to the reader.
I will pay an small amount per article, and if I am satisfied with the quality of the articles the collaboration could continue with an article every week (or more). (4 articles per month at least)
If you are interested about security, penetration testing, ethical hacking, etc. this is a great opportunity to stay updated by writing some articles.
Thanks
