AIR Messaging Client

I want a messaging client developed in Adobe AIR. This is basically an email client, but communicates with the server-side using BlazeDS; so the client does not have to know the SMTP or POP protocols. The messages must either be text or html with attachments as well as PDF documents that can be uploaded/downloaded and displayed in the client. The application must be developed in the Cairngorm or Swiz framework and must include unit tests for all the actionscript as well as java classes. The UI must be based on the same model as MS Outlook with a tree on the left, a message grid, and message view components. The normal functionality must be available i.e. searching of messages, sorting. The UI must also be able to handle multiple languages. No skinning is nessasary as this will be done by ourselves. The backend must be BlazeDS, Spring, Hibernate and MySQL based. All the messages from the client must also be stored on the server. You are welcome to contact me if you require more information.
