Need a programmer to build event search engine site

I am looking for a website programmer who can help me to build an event search engine with some added features. Here is a reference to the event search engine that I am looking for (this is without the added features) <[login to view URL]> I am a graphic and web interface designer. I need someone who can help me with the programming part. Some added features include each event posted by the organizer will be pushed to the its Twitter,Facebook account and its site. Besides, it will also send a reminder to all the members in the organizer's database before the event. It will also have a user log-in/database. People can sign up and subscribe to an event. A QR code will be generated once people subscribed to an event and this QR code will be sent to the user's phone. People can check-in into an event using the QR code. The QR code will be scanned and registered in a database containing all the information of the attendees.
