You're site's over a month old, I don't think you want to taint it with spun content. It's better to get unique content written, if you really care about your site. I use Textbroker.com. I usually set my content at $0.016 per word 3 star rating. The double benefit trick I use is I order content between 800 to 1200 words. Only people that love writing would even attempt to take that task, so I get 4 and 5 star articles for 3 star pricing. I don't go to 2 stars, since it's a read and disapprove and resubmit that crap. The grammar is bad, and it's just people that don't know English trying to make money. Textbroker is the way to go, it's cheap enough for anyone. If you order content below 600 words, you can get a wise variety, but only top producers seem to want to attempt to write above 800 words. Just my take.
In terms of the case studies, I don't recall exactly which one you are referring to, but your site is one month old, and if you don't know more than the basics of ranking or SEO, you can't take what they do and attempt their feats, since you might miss basic steps that they didn't spell out exactly in the case study, like hiding your footprints, or making sure you're not on a shared IP and in a bad IP neighborhood.
