Custom Greeting Card Builder Website php/mysql javascript flex

I am in need of a programmer to develop an online photo card / greeting card customization website application. Sites similar to what I am looking for are: [login to view URL] [login to view URL] [login to view URL] The user will choose from various templates (i will provide the templates - designing templates is not part of this project), the user can then add text, edit text and fonts, upload images and arrange and edit them on the card. After creating the card, it is saved and added to the shopping cart. I will need an administrative back end to manage the site and receive the created cards. Looking for an experienced programmer who has developed similar applications.
