This doesnt have to do directly with flash but I was wondering if someone could help me out.

I'm currently in talks to work on an eCommerce site.The client would like for when a customer orders a product online via credit card, it be delivered by email automatically. (it would be a file such as a wav.)

The file can either be attached to the email (preferred) or a link may be included in the email to a temporary directory when the consumer may download his purchase.

Any help would be much appreciated.
