Amazon Keyword Ranking I PAY A LOT $$$

I am looking for some one who knows how to get my product to the top of the first page for specific high searched keywords. I prefer some one who can do this without using fake buys as the main component. If you know how to rank my high volume keywords I will pay you per keyword that you get on the front page and big bonuses if you get it top five. The tougher the keyword the more I will pay you.
