Link cleaning SEO work to resolve suspected google panda/pengiun issues

We are a startup (ecommerce marketplace) and suspect after we recently changed domains that we are suffering from pengiun/panda issues with poor quality links coming to our site.

We need a link cleansing operation to start immediately which will involve:

1) Using suitable tools to compile a list of known links
2) Having experience in identifying which links are problematic
3) Emailing webmasters/bloggers at a fast pace (including follow up emails) to ensure links get cleansed

In order to cary out this work you must have several years SEO experience, and must be very experienced with specific panda/pengiun issues. If you have to look this up, please do not apply! You should have carried out one campaign specifically on link cleansing previously.

The person getting this work will likely be hired ongoing and will be given further work over the next year.

IMPORTANT - before bidding on this project please ensure you post a comment with your bid exactly as below. Please copy and paste the full question and answer in your comment. If you don't do this unfortunately your bid will be rejected without being read.

1) List all of the tools you would suggest using to recognise problematic panda/pengiun issues, organise which to chase up, and then follow up via email. Be specific on the name of the tool and one sentence on what it would be used for.

2) Do you think using the disavow tool is helpful for this campaign? Either way, explain why in a short paragraph.

3) When discovering a backlink, tell us what specific metrics and process you prefer to use to establish whether the link should either be kept where it is, updated, or removed entirely.

4) Give and example of one other link cleansing campaign you have carried out, and what the results were. We will ask for a reference to confirm this if you are selected so please ensure you are happy to provide this otherwise please do not bid.

Look forward to hearing from you!
