Login for Twitter using oAuth

I would like a way to allow people to download content from my website, but when they visit the site, they will be presented with a page which asks them to login via Twitter's OAuth, and given the option to follow me (with a checkbox). For an example of what I want, please visit this page: [login to view URL] It asks you to login and presents you with a download for a free MP3. I already maintain API access, but I lack the script to accomplish this task. This would be composed in PHP. Please bid fairly. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Employer will receive exclusive and complete copyrights to all work purchased.
