iPhone Web App MP3 store

Hey, I need to setup an iPhone web app and mobile phone (Android/Blackberry) optimized website with a nice/materialistic design. And would love a desktop version also available. Consisting of 4 pages. 1) I want a news section on the front page to post my new tracks info on it. 2) I would like a shopping page where I can sell my MP3s. I would love the layout to be similar to Amazon (example: [login to view URL]) with sample song and buy single tracks or whole album. 3) And I would like to have another page where I can post free MP3s, which again can hear sample of it and a download button. Each files on this site separated from the others by date of post (files posted on the same day grouped together). 4) I would like a page template so I can later use it for any additional sections I would like to add. After every purchase, I want an encrypted link that is valid for 10 minutes to be sent to the buyer's email to download the mp3. I need the whole thing to be easily manageable to enter new data on my own. Logo/Icon design will be needed.
