I understand you are looking for a push button solution that can generate unique articles in the quickest time possible, and hopefully with little or no cost. Nothing wrong with that. If there is really such a solution, I would use it as well.
But so far, this kind of solution just doesn't exist in the real world. At least not for now, and probably not in the near future. None of the spinner software can do it.
The best push button solution is probably Article Builder but even that is not 100% perfect. So for your money site and first tier backlinks, you will have no choice but to write them yourselves or pay someone to write the articles for you.
Obviously, for your money site, the content must not only be unique, but ideally should be good enough to convert visitors into buyers. Therefore, you will have to spend more time on it. 10 minutes is probably not enough to generate a top quality content.
For first tier backlink, the article just need to unique. This kind of article should be pretty easy to write and shouldn't take more than 10 minutes per article.
