500 Back-links Needed

I'm looking for someone who can build 500 backlinks to my article using keyword as anchor text. I'm looking for a variety of mix in the sites that link back to my article site. These can include but are not limited too forum signatures, blog commenting, social bookmarks ect. I'm not requiring for these sites to have pagerank, dofollow, or traffic, but If you can get me at least 1/3(166) of these sites which includes one of these elements a bonus and more work in the future will be available. I will send more detail info to worker selected for this project. Also must document in spreadsheet were were the link came from and if its just a plain backlink or includes one of the elements I talked about.
