I have a client who is looking for a system where their customers can download tender documents (eg PDFs and DOCs). The acquirement are however that each user must have their own access details, and agree to particular terms prior to downloading the documents. There is probably up to 5GB of documents they need to store. The documents must also not be able to be downloaded via a link without entering a password first. My client must be able to easily upload and manage users too.
Anyone aware of any cloud services that offer this type of service? One I have seen is box.com, anyone use this?
They currently have a basic system that was custom developed for them, but it is very old and not supported by the new hosting they are moving to.
