OSCOMMERCE: Create Instant Download Mod

The internal instant download mod for OSC is crap, and I will not pay if you use it. I am looking for a secure Instant Software/Script download mod that allows instant downloads once payment is rec'd. Payment options should include: paypal google checkout 2checkout AlertPay with options to disable/enable. test mode, paypal has a sandbox for testing, I need to be able to test as a pre-tend buyer, once complete, then I am shown the download info. option to enable/disable mod should allow and account for multiple orders, and once payment is rec'd, then the appropriate downloads are given/sent. Organize File system...in OSC you dump all your files in just one directory, then setup...not going to work. I need to organzie zip files into caegories... IE: /downloads/ /FreeStuff /SEOTOOLS /PHPSCRIPTS in this mod, I wish to offer free downloads, any price set to $0 must be considered free download, and bypass any payment systems, and proceeds directly to download file that has been setup. payments are to be fully secure and validated before the issue of any download links. download info should be time based IE: Expires in 3 days, can download 3 times, etc. Comment your work so this MOD can be updated if newer versions of OSC were to come out. Mod must be completely Installed/Working. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
