Add Feature and Modify Design of Custom App

I need a new feature added to a custom music player app as well as the design modified as per a psd design I will supply. Please look at the attached mockups to get an idea of the changes I need done. Please also visit the app here: [login to view URL] (you can test the app out by registering an account and then dragging and dropping an mp3 onto the page). This is the feature I need added: * Ajax Edit in Place: Using this plugin: [login to view URL] - I want users to be able to click an edit link and then be able to edit the mp3 track names. Please look at the screenshot to see a mockup Design modifications needed are: * New login Screen Design - the home screen of the app needs to be modified as per the psd I will supply. It is a basic change. (see attached [login to view URL] for demo) * Welcome message - When a user first registers a message should be displayed to the user, and then disappear when the user uploads their first track. (see attached [login to view URL] for demo) Ongoing work will be offered on this app if work is completed quickly, cheaply and to a high standard.
