Simple data entry of website information

I am looking for a competent person or company that can carry out some basic research into the backlinks of 4 websites. With each website you will need to find the sites that link to the website using the site:[login to view URL] command in Yahoo. You can also do this using firefox plugins or other software. You will need to create a spreadsheet detailing the following information for each backlink (sitewide links will only need to be entered once): - Url - Whether the link is Sitewide or not - PR (Of homepage if sitewide) - Domain Age - Link to advertising/sponsorship page (if applicable) - Contact email address This is simple work and should not take more than a couple of hours so would like to keep the cost as low as possible.
