Site List for Posting - Pligg, BuddyPress, Drupal, Social Engine, Elgg, Wiki and PHPFox - repost

I am looking for a Freelancer to help me build some Custom Site Lists for an automated software (Backlink Beast). I utilize the current default site lists - but I need to find some topic specific sites that will work with their SEO automation. The types of sites that are compatible are Pligg, BuddyPress, Drupal, Social Engine, Elgg, Wiki and PHPFox .PHPmotion I will need a Freelancer to search the web for sites that allow membership/posting for the themes of The Arts, Artists, Art Galleries, Artwork & Paintings, Interior design, Home improvement, arts and crafts, home and garden and home decor.. I would like to find at least 2000 sites in total, more would be better. Deliverable would be an Excel file or Txt file (with urls on separate lines) There must not be any URLs in the list that are irrelevant to the subjects listed above.
