simple asp download script

I need a simple asp download script: I sell MP3s to my customers, and I always sell a package of 2 MP3 files + 1 text file together, so the script should send these 3 files together after the customer - after payment - has clicked on ONE url that he has received. If zipped, the files should self extract. ## Deliverables Fully functional script. Setup, or help with setup on my server.
