How many articles do I need? - Rankwyz - 20 diffirent posts

Hello, I'm just starting with FCS Networker/Rankwyz (I'm buying the first one probably). So I need articles for my private blogs. I want to promote 20 posts about diffirent Android games. Now, I now I can spin and scrape content, but most of the games doesn't have articles about them online.

How many articles do I need for first month? I can write some and buy some. But where will I buy article about so specific subject like not popular Android game?

There are a lot of services to buy articles here ,go search here http://www.blackhatworld.com/blackhat-seo/f194-content-copywriting/ and 3-5 article per week is ok.

If you have 20 posts on your site and you want to promote them then you'll probably want more than 1 link per page.

I would say 200-300 links per month to those 20 pages would be a good start (10-15 links per pages), which means you'll need 200-300 articles per month, possibly more depending on how intelligent those software are (some software will post random articles and you could end up with duplicates, not so good)
