I have a website that sells custom mp3 loops for live music (about 400+). They are all stored in Amazon S3. Customers will buy either one loop at a time or many at a time.
I need someone who can create an Add to Cart script that enables the customer to download the file(s) after they've paid, using a dynamic url that expires in 48 hours and can be clicked 3 times, sent by email. They will check out using PayPal.
