Article submission link building expert

We are looking for an article submission expert who has a large list of high quality pr sites to build back-links with. They will be informative articles that link to pages of website domains that coordinate with each article. We expect to see before releasing escrow a report that lists the approved url's, which show where the article's were submitted and showing live with links (not just the main domain where submitted , but the full url where article page is on that main domain). These are article and social bookmarking links, not directory links, so we only want to pay for approved submissions. Please let us know your best price for submitting getting 50 or 100 guaranteed links per artcile. We will have much more work for the successfully proven link-building professional in the future. If you have some other great ideas for increasing traffic and building links for a better website SERP listing, please advise and we will consider. Thank You!
