Well first of all you need to pick a server side language. If you already have a host, find out which one(s) they support. If not, read up about them on the web, pick one and find a host that supports it. (I highly reccomend ASP.NET).
Setting up a payment through paypal involves the following:
- Gather your data (i.e. what item the user wants to order, how much it costs, etc)
- Forward them to the PayPal payment page, passing a few parameters in the query string. These include your PayPal ID (where the payment is being sent), the amount, invoice number, page to go to when complete, page to go to if the payment is cancelled, etc.)
- As you are doing instant downloads, you will need to look up how to use PayPals Instant Payment Notification (IPN - see PayPals site for more info). This is where PayPal will make a request to your server after the payment has gone through so you know that the user hasn't just copied the Return URL and gone straight to the download page without actually paying.
