Help choosing a platform and implementing the features of for a non-academic, non-scientific online article blog

I am looking for a professional to help me choose an appropriate platform and implement its features for my online article blog. My primary goal is to provide valuable information to a specific audience, so I need someone with expertise to select the best platform. Furthermore, I need a user-friendly content management system that is highly customizable in design and provides advanced analytics capabilities. I do not have any specific platform preference, so I am open to all suggestions.
I have a detailed description of the blog and its management that I'll provide to the applicants. See attached.
