Secure Download Script

I need a secure download script for Paydotcom that works the same or similar to "Easy Download Protector". * Customer should be taken to a secure page for sign up after finishing payment with Paydotcom. * Their log in should be using email address and a selected password of their choice. * Time limit on download area can be set from 1 day to forever. Script has to integrate easily with any html page. * Script has to have an easy admin section for editing and removing customers and details. * Script can easily broadcast an email to all customers or one single customer using the customers firstname. * Script must be able to add multiple products, upgrade and downgrade products. * Script must give access to product/download immediately and send out confirmation/welcome email. * Must integrate with [login to view URL] as easily as possible.. Preference will be given to a script that can also easily integrate with paypal, clickbank as well as paydotcom even if it is a slightly higher price. If you can do just "paydotcom" or all three payment processors please place this in your bid and tell me if their would be a price difference between the two if any. I don't mind if the it is an off the shelf script that is modified but it must work without bugs. Similar experience in this type of work preferred, secure download, payment, membership scripts, etc. I don't have much experience in this area but I think "Easy Download Protector" is written in perl ([login to view URL]) Thank you. ## 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 (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
