Create thought-leadership article on programmatic advertising

I am looking for an experienced content writer to pitch an angle and then ghostwrite a thought-leadership article (900-1,500 words) on programmatic advertising.
The purpose of the article is to demonstrate expertise and authority in digital marketing.
The target audience is senior marketing professionals, such as marketing managers and directors (may have some knowledge of programmatic but have a broad knowledge of marketing rather than specific topic areas).
