Seeking Plugin Advice

Simply, I am looking for a plug in that will allow me to share files and large videos privately with my customers.

Technically:

• Customer will have their own log in credentials.
• They will not go through or even see my site’s Dashboard.
• After logging in, it will redirect them to their secret file folder / page.
• The secret page will have branding options to match website.
• They will be able to upload and download files.
• No one can just register, I will register each and every customer.
• Customer will only see their secret page and not other clients’ files.
• There should be no file size or bandwidth limitations with the plugin.

Thank you in advance for your help!
