Advanced File Host

I need a file hosting script that allows visitors to register to gain extra benefits. Guests should be allowed to upload files, but they should have a capped file size and number of downloads. Vititors will be able to optionally send an email to someone with the download link. I need to charge for membership via paypal only. Paid members will have a larger file size limit, and will have unlimited downloads. I need the settings customizable in the admin panel. In the admin panel, I will need to be able to add and delete users, change file size limits, delete files, and change general settings. ## 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.
