Social Bookmarking

I need my website ([login to view URL]) submitted to as many high ranking social bookmarking sites as possible (at least 50, [login to view URL], diggs,Stumbleupon,reddit,Newsvine etc [login to view URL]). I would like the bookmark on each site to be validated by few accounts to push up. Additional Information: a) You must have a list of high rankning social bookmarking sites (please provide in pmb before accepting bid) b) You must have old accounts (not new accounts) c) Submission should be done over a decent amount of time to avoid being flagged by google (30 days) only a reasonable bid will be accepted
