We have had an unfortunate negative online business review shown on a low grade, no name site, that has impeded our business growth. As we are a relatively new company this shows up on either the 1st or 2nd pages of Google when our Company is searched. I want you to remove it... Only serious bidders please with this experience.
I am not sure hiring a hacker is the way forward, not sure you will get your desired result, what you need is a reputation management company to sort it out for you, there are a number of ways to do this, just find a quality reputation management or just a plain SEO consultant who will bury this for you, I hacker cannot really remove it if the feedback was left on a large company review site.
I would avoid using any hacking techniques. These are only temporary and the site owner will find out sooner or later and most likely not in a good way. Hacking can get you in serious trouble. I would recommend using reputation management aka reverse SEO
