HtmlUnit:Multithreaded login to facebook follow link on App

Using HtmlUnit and Selenium (or any other web testing framework) I need your script to login to facebook using an account list I will provide. Your script should then follow a URL that is visible inside an app and then submit a form inside that app. The entire thing should run in as many threads as possible, the form should be submitted from different facebook accounts in the shortest timespan possible. The URL in the facebook app will only be accessible for 45minutes per day, for the next 3 days. I will provide you with a short script that monitors the website and notifies you when the URL in the facebook app is accessible and your script should start. All pages are plain HTML/Javascript. No Flash. All logins should be performed through a different proxy. I will provide you with access to a clean MySQL database with HTTP and SOCKS proxies in it. Your script should have a proper form of error handling so if a proxy is slow or dead, it should quickly change to the next one. (Again, time is very limited) Probalby using SocksiPy will save you some time. This project is urgent, I will close it and select a winner tomorrow. So please only bid if you have time to start RIGHT AWAY.
