Conversion tracking for E-commerce (keyword level)

I need a software program that can be installed on any website I choose that will do the following: For site visitors that use Google to search, the keyword / key phrase they used to browse to a given website needs to be tracked and recorded, and the user needs to be cookied somehow so I can see not only which visitors performed a specific action (converted either through filling out a form, reaching a certain page <shopping cart>, etc). I need to be able to track the pages visitors visit and where they start and where they end up by the KEYWORD they enter into Google to come to the site, NOT by their IP, NOT by any other method, but by KEYWORD. So far, Google analytics does a good job of showing how people come to and navigate a site, but it doesn't show goal conversion by KEYWORD. I am not sure how to accomplish this, so recommendations are in order. Do not respond to this bid with generalities, stating "we can accomplish anything you desire or we have experience in this area". I need specifics on how you will accomplish this, and confidence that it can be done. Non-specific bids will be ignored, so please don't waste my time or yours. ## Deliverables I forgot to mention that I need a dashboard view of the data being collected using the program. The dashboard will be viewable by day, week, or month, and will show a list of keywords, how many visitors came in on a particular keyword, and how many of those visitors accomplished a defined goal or goals within the website.
