Adsense revenue optimization

Hi, I am looking for a seo/sem expert for optimization that will bring me higher ctr and better ecpm from google ads on my site. This is a video website with over 3m video pages. i am looking for an optimization "only" for my video pages, not all site. These are generic pages so the solution should also be generic for all pages, not page spesific. White hat optimization only, no keyword stuffing, spamming, cheating. Adsense reports are updated frequently so monitoring success is easy. I will escow your payment at the beginning of the job and release it immediately after the targets are reached. Please bid only if you have done similar tasks before and have references to prove. I will share more details about the site with owners of acceptable bids. Thanks.
