Crowdfunding and PayPal Adaptive PaYments API

This job has two parts: I want a script which provides a crowdfunding function to my wordpress site. The elements to be returned to the crowdfunding pages are those you would expect- money raised, percentage of money raised (I have a thermometer image), number of contributors, number of contributors. include any database records and an easy way to keep track of funding activity via wordpress. Part Two involves setting up with [login to view URL] an Adaptive Payments API with chained payments and preapproval authorisation storage. This project would suit someone who has already done this before, even better if we use an API that has been approved in the past as a template (for faster PayPal turnaround). I also need someone who can communicate well and in reply indicates that they understand the project. I would like the project to start and finish in September 2012.
