Simple facebook account verification form

Hi I have a website already. I need a script made that will verify if the a submitted facebook profile URL is real. - The form will ask for the Facebook URL and the user will then click submit. - A simple progress bar should be shown (something like [login to view URL]) and the script should connect to facebook and check if the facebook link is a real profile. Example Real: [login to view URL] Fake/invalid: [login to view URL] - If fake/invalid, the form will say this. If real, the form should display their username. - If real, a new input box will appear which will ask a question. They will submit an answer. If correct, display some text, if not correct, display 'Incorrect' That's it. Lowest bidder will win.
