OK, since you liked the work, would you like to write an article on book marketing for Reviews for Medium Featured Books? Check out the book marketing section. What you write will stay in a reasonably short list of articles; we'll not be publishing article after article in this section so that older ones get buried. These will be the best how-to articles I can find. I know yours will be one of the best even before you write it. I've added you as a writer to the pub so all you'll have to do is submit your article.
