Newbie-ish author with an article marketing question

My name is Paul. I've done article writing for public and private clients for over 5 years. Now I want to venture out and market my own e-book. I've already got it published, set up a website, put it out a Kindle version, etc. I am very new to IM, but after reading this forum and looking into some of what my clients have done, I think I can take hold of article marketing and make it work for me.


What I want to do for my book in terms of article marketing is to target it towards hobbyists and enthusiasts in just about anything. Knitters, foodies, muscle car builders...I believe that if you are passionate enough about something, someone will pay to read what you know about it if you have basic English skills.

I tried this technique today that helped me create 60 articles in 2 hours. I just don't know if they would cut the search engine mustard and I'm not sure where to put them.

So I need your help. (sorry this is long). Here's what I did. I wrote a 400-word article on "How to Get Paid to Write About Your Knitting Hobby". I wrote it in 4 sections: A- the intro where I talk about getting paid and show my credentials; B-the "here's how; C- the "localize it, where i talk about how to market it for your specific city; and D- "the close", where i work in my website. It's the formula I did as ghostwriting for a friend and he liked it.
What I did next, though, was write 3 totally unique versions for each section except the localizing one. Then I labeled each one A1,A2,A3; B1, B2, B3; and so forth. After that, I started interchanging them all and came up with 19 variations that involved each section plus the unchanged local one. All of them still flowed and were still readable articles about how to be a knitting freelance writer online.
THEN I copied the doc to another one and did a mass-replacement of "knitting" with " muscle cars". Still worked. Did it again for another topic and it still worked. In the end, about 60 articles.
(man this is long!)
SO now that I have these 60 articles, what is the best way to put them out there to drive the backlink traffic without them looking as duplicates? And I'm not asking for FREE way because I'm not above paying for a service. I just want it to work for what I've created without tripping up search engines. Do I just outsource them to some Filipinos to backlink to free article sites, or do I go with a program like UAW and load them? Or is there another program that would do even better?
Thanks for reading!
