How do you scale up article marketing?

I just discovered the difference between article marketing and article directory marketing a few weeks ago. For now, I can write 7 - 9 quality articles a week. I wanted to know how do you scale up your article marketing results without working more than 10 hours a day?

I am thinking of hiring ghost writers and a virtual assistance to get websites and offline publications where my articles can be published, does anyone have any framework or ideas on how to scale up article marketing to get more results.
