Hey guys how's it goin?

Im working on putting a lil business together online and e-commerce site to be more specific and I have a lil problem because i dont know much php and i dont want to bother my partners with this project. So im looking for a script to do the following:

*the script needs to automatically e-mail a zip file to the person after he/she pays via paypal

thats all

So i was wondering if there was a script maybe i could pull off hotscripts.com and just edit to my needs or if you guys have a better solution.
