Develop website to sell E-books-Audio needed

I want to develop a similar website to: [login to view URL], however, I will only be using the English Language. My books also will not appear on shelves as on this website. They will be just displayed side by side. When the user clicks on a book on the main page, they are taken to a page where they can click on the little speaker and hear my audio describing the book. I will need an admin section from where I can add new e-books, enter book detail, upload audio, upload e-book , (to be downloadable after payment), set price of e-book etc from admin section itself. I need to be able to view the orders/payment received from admin section. the frontend is to be fully dynamic based on the e-books added by me from admin section. Note: I already have the domain name, the website header and the deluxe hosting from godaddy.com. Bidder should provide samples of some websites they have developed.
