Digital Delivery For Drupal Membership Site

I have a membership site set up through Drupal at [login to view URL] and I need some changes or additions to be made. What I offer there is: 3 different levels of membership digital downloads each month highest paying customers get the most downloads download links (externally hosted) are removed after 2 weeks those past products are available for purchase I have member's pages that have the product download link available for members. After two weeks of the product member's page being available, I want to switch it over to a product page, where the user will have to pay for the download link and have it automatically delivered after Paypal payment. It's very likely that users will be purchasing more than one product at a time, so I'd like to automate the delivery of every product purchased. Basically, I need some way for my customers to receive their download links (which are hosted on my file hosting site) immediately after payment. Maybe there is some way to block part of the product page (where I would put the download URL) and make it fully accessible only after payment? My maximum bid for this project is $70. Payment will be made (through Escrow) after the project is completed. I would like to have this done in 10 days or less. ## Deliverables 1. My membership site at [login to view URL] must be fully functional 2. My membership site must allow anyone with a free account to buy products that I put up for sale (paid members already have a discount) 3. Every product must be automatically delivered after payment is made through Paypal. 4. This work must not interfere with any of my currently existing functions. 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. Buyer will receive exclusive and complete copyrights to all work purchased.
