I am looking for a website similar to rankpay.com. Specifically, you will need to install the google adwords traffic estimator API and all other scripts required in order for the site to (1) determine your current ranking on Google, Bing & Yahoo and to (2) work out the difficulty on reaching different positions for your desired keywords.
The script will have to use an algorithm to determine instant pricing for clients too and proceed to a paypal payment gateway once the client has picked a keyword and quote.
