Music Player For Selling Beats Online

I want a mp3 beat player for my website so that customers can scroll through my beats and purchase if they want. Here is a very good example of what I want made - [login to view URL] This example covers pretty much exactly what I want my player to be like, accept for the graphics and a few option fields it has. Here are the main functions that I want in the player - - Fully integrated with PayPal so that when a customer buys, they are sent to a download page where they can download the beats they just purchased - An "Add to Cart" function (I have DL GUARD, so we can figure out what is the best way to go about this function) - A visual screen just like the example I gave in the link above to go with each beat that is being played. So that pretty much sums up what I want. I need this project to be completed for me with a turn around time of no more than 4-5 days.
