Modifications for Cubecart based shopping website

We deal in the sale of MP3s, using Cubecart, and would like the following modifications and add ons for Cubecart which can also be modified later on to use with other PHP based shopping cart scripts 1. A search bar that prompts suggestions from our database of products, as the customers enter their search query. Exactly like the search bar on this website [login to view URL] In addition, since our products are not in English and are transliterated in English, the suggestions should also give alternative spellings for song names. 2. A button that enables customers to preview the respective track on each product page and product listing. Again, something like the way it is integrated in this website [login to view URL] For the backend, a new column should be added in the inventory table for us to provide an ABSOLUTE LINK of the sample file. There should be an option of adding or not adding a sample link on the add/manage product page. 3. The products are listed on our website in the standard format that Cubecart offers. You can get a look at it here [login to view URL];catId=saleItems It has the product image followed by a short description of the product, the price and the buy & more buttons. We would like the products to be listed with their details in storable columns. For e.g., product Image, Song Name, Album name, Artist name, Price, followed by the Buy and More buttons, where the customer is able to sort the Album, Artist and Price columns according to their preference. We will furnish more information, details, and live links of our website once you correspond with us. We also have a lot or other PHP related work and will prefer to award to the person who completes this project successfully. You can also bid for one part of the project.
