I have over 4 years of experience with Google Webmaster Tools and I've already used the Disavow Tool to remove more than 30k links (from porn sites and low quality domains). The site has recovered over 85% of its previous state for less than 2 months and is still in process of recovery.
My price quote is subject to change depending on the work that needs to be done. I'm open to discuss the project.

D. Dimitrov
