SEO - doorway page system and backlinks

Hi, I own a dating site and I want to be ranked for specific regional keywords. I've seen several dating sites doing this by building doorway pages with profile content that may or may not be actual users serving as the unique content of each page. They have also used subdomains and built many backlinks to the root of each main doorway hub page. Here are the examples: [login to view URL] ??" all in the top 5, barely any external links: [login to view URL] [login to view URL] [login to view URL] I believe they are using fake testimonials with scrambeled text to generate unique content for each page. Then they are linking to only a few other pages within the network of pages to avoid too much cross-linking. I would say [login to view URL] and [login to view URL] are doing it similarly and very well. I need an expert in SEO to do this for my site as well. Please bid only if you have done something like this before or have the right kind of SEO knowledge to do this properly.
