SEO Google | Reputation Repair

I need someone experienced to repair a google search reputation quickly. Our site is ranked 1st page on company name search BUT 2 negative blogs take up the rest of the page. I need someone to SEO/viral market our company name so that we take up the first 5 pages of Google and that the negative blogs are wiped out! We are a small business, been in operation for 5 years and this is happening to a new brand we've just launched. It's a small but IMPORTANT project - timeline on this is immediate and I need results on google within 72 hours! Give me a suggestion on time, strategy and cost.
