Totally agree with everyone here. I wouldn't, under any circumstance, pay for a link to be removed. I was reading a blog post written by Google the other day about it. http://googlewebmastercentral.blogspot.co.uk/2012/07/new-notifications-about-inbound-links.html
Matt Cutts says in the post "In a few situations, we have heard about directories or blog networks that won't take links down. If a website tries to charge you to put links up and to take links down, feel free to let us know about that, either in your reconsideration request or by mentioning it on our webmaster forum or in a separate spam report. We have taken action on several such sites, because they often turn out to be doing link spamming themselves."
Google are good at spotting these types of links and not counting them especially if there is a strong backlink profile. I'd just disavow at domain level.
