SEO expert on google ranking required

We need a professional SEO expert who understands google's algorithm and effect of changes (panda, penguin..etc)....we have had several sites hurt by changes made by google about 5 months ago and now need to start rebuilding back to 1st pages. There are specific URL's of our websites that need to be looked at and then ranked higher. Most of our pages/websites rank at this moment on page 2 or 3 or higher. Of course we require only whitelabel and Google approved methods. We would like to start with 5 keywords to test. Payment per keyword when page 1 rank is established. Please bid for total project. So when you bid 120 dollars, price will be 20 dollars per keyword. The ideal candidate/freelancer will have extensive knowledge on all SEO topics and strategy. We will not respond to canned responses and people with no feedback. Only serious replies/bids/private messages will gain a response from our part. Thank you in advance.
