Omg, listen.. just do this if you want to rank. Get a few domains expired or so that have medium/high PR and put unique content on each domain. Put each domain on a different hosting company, just cheap hosting. Then link to your money site with varied anchor text 'of your keyword' using upper case/lower case, brand name, url and variations, don't repeat the same anchor text but use the main keyword you want to rank for in the anchor some where. Every week add some more unique content to your high PR sites and you'll just continue to rank. It's really that friggn easy.
