Thanks everyone for the feedback. So it sounds like it doesn't matter what keywords and quality you have on your Web 2.0 as long as it will look suitable for a manual review by Google.
So this works for me then. I don't expect the articles will have have a bad quality to them, but you never know when buying cheaper article writing services online. I also was just not too sure what I should be providing for a niche/title to the writer, but by the sounds of it, it won't matter too much as long as it's somewhat related.
