i have been running aaronbeats.com for a few years, and am looking to add more php functionality to the site.
what i need is the ability to:

upload a .zip or .mp3 files to server, apply name and info to it and automatically create a product with a buy now link attached to my shopping cart system, and automatically apply a short audio clip layer on top of it for previewing purposes, and automatically place it in a table with the category for it, while at the same time creating the 'preview' buttons and 'buy now' buttons next to it...

..this will be to make it easier on me when i want to create a new product without even having to open up dreamweaver. i want to be able to login in my browser and upload and create a product that is automatically placed without opening any of my web applications.

my website is: www.aaronbeats.com

for reference, check out the way that you would upload beats on www.mybeatshop.com or www.rocbattle.com
