Great blog post!!!
I'm not sure about the title though.
This requires some extensive writing of e-mails, posting jobs and correspondence with freelancers which all could take days and total well over a single word. How much time did this take and how much did it cost? Or does this not apply to the post we read? After reading, I expected it to be videos or a series of videos.
On a more positive note, sometimes a video is much more effective than composition alone. I believe the search engines heavily favor visual content as well. If a picture is worth a thousand words, how many is a 7 minute video worth?
How can you apply this type of marketing to the content you cover? It won't likely apply to every post, but It could be just what you've been missing on some. Write down what your expectations are, and afterwards measure the results. You might try a performance test on an older and popular post (you should have some metrics to compare), repurposing the content with videos.
