Update existing links to our site, find new link partners

We need to alter the link descriptions on sites that are currently linking to our site to be more in line with our current website offerings. This job involves: 1) discovering high level relevant links to our site using google, yahoo, other search engines using specific search phrases. 2) personally notify the owners/moderator of each linking site with our new desired description, we will furnish the new description. 3) document the date of contact, the site contacted, and check back in 1 week and/or 2 weeks to verify the link text was altered We realize this can be a very large project so we will limit to the first 200 links to our site. 4) find 100 suitable/related websites and request links from them, we will furnish the request text. We DO NOT want link-farms or any black hat SEO tricks.
