Need some suggestions about Video Downloads or Hosting?

I have a possible client looking to have something done by me and I am looking for some suggestions if possible. I have no problem with designing the pages but they want me to maybe host videos for them ect.....

Here is what they have asked if I can do, please feel free to comment and give suggestions to me.

1. A simple one page sales page - with a paypal link designed. Once the payment is made via the paypal button they want - a window that should send the purchaser to a page where 8 videos will be hosted to download.

2. The video's product page should only be displayed to
those who make payment. It can be a unique id and password or it
should be made available to only those who make payment.

Second option is

1. The one page sales page will give way to a video sales page - very
little text with a 10 minute video selling them with a paypal link.

2. Once payment made, they go to a video page where they can stream
the videos and see the product they bought.

The main thing is that the videos should not be viewable by everyone ONLYfor those who buy the product?

Can this be done?

How would I do the hosting for the videos and make them protected, either downloaded or hosted to view online?
