Need an advanced php developer to run tricky facebook commands

facebook requires a hidden 'dtsg' token to perform all actions on the behalf of a user. we need you to write a script that can do one or all of the following given that we will supply the users' dtsg token: create an event. invite all friends to an event. post on wall. upload an image and tag friends. tag friends in posts. comment on friends' posts. message friends. send chats to friends. please bid on one or all of what we need done. this work is for someone that is very verse in php and can read facebook's javascript to figure out how to make the appropriate calls to fb in order to execute these commands. our script will supply the dtsg token (and phstamp), your script must execute the commands with that token.
