Facebook Application

I am looking for someone to create a Facebook App in PHP that will store data items that users volunteer. It will store the data in a MySQL database. Users will then have data items recommended to them based on their similarities to their friends/other Facebook users.

For example, Mary likes Apples, Bananas and Clementines.
Joe also likes Apples, Bananas and Clementines. He also likes Dates.
The application will recommend to Mary that she might like Dates too!

The application will post on people\'s wall when they have typed in a new data item and invite new users that way.

Many more details to the chosen developer.

I need someone with a good understanding and track record of creating Facebook Apps.
