Classified Site

The project I am creating is a website/facebook application. it is a classifieds type page. (that can be built off an old clone as long as facebook app integration is there) users can only register for site being a facebook member (login with facebook Java SDK) users will search post based off location using their zip code (what ever classifieds are closest to them will show up on search results page) (users should be allowed to adjust the distance they are willing to travel for their search 10, 25. 50 miles) once a user finds a classified they like they can contact the person who post the classified by email or the number listed. I would like this site to be similar to [login to view URL] but all content will come from users posting and commenting (facebook open graph). all the page design layouts will be completed by me in photoshop and do not need any design work done. just need you to convert to html5. must be able to skype meeting.
