Hello sir,
I have done so far the projects you are looking for to be done.
You will give me the access to your webmasters tools where i will check every domain that point to your website.
You wrote you have 1.000 links that point to your website, but how many domain are point to your website?
The price and number of hours depend on the number of domain that point to your website.
If there are 1000 domains than i believe, it could be done for 40 hrs.
I will go trough every domain that point to your website, identify which one are bad, and make a list. Than we could contact some of the websites, but according to my experience, bad websites are made for link building and usually webmasters gave up of them and they become link farms and it is hard to find a webmasters for link removal, but we could try to contact, wait a while and then submit the url in disavow file for submission to google.
I will create a file, with links, and with a comment about every link, why it is in the file and is the webmaster contacted or what.
Look forward to your reply,
Best regards,
Ivica Cvetkovic
