Adding to existing website: member-area and music downloads against fee

Hi, this project is about adding pages to an existing website. First part: A page where users can listen to songs has to be added to the existing website. The songs are long -up to 60 minutes. The user can listen to a few minutes of the song. If he wants to hear the complete song he can buy and download it. Maybe it is requested that a copy and play protection guarantees that the song is not copied / played more than 5 times. The user pays with CC or Paypal. Https is needed. Second part: A 3-level membership that gives access to an area on the already existing website. The general part of the website remains open to the public. It should not be very obvious, that the public part has been left, when the user has logged in to the member-area. I think it can be best compared with ebay. Once you're logged in you have extra options however everything looks mostly like if you are not logged in. The member pays a fee for the access to the member-area. There are 3 levels. These are examples for the differences between the levels (only examples!): - Lowest level: [login to view URL] and download one song (from the sonf page) [login to view URL] in the shop (for products chosen by shop owner) - Medium level: [login to view URL] and download several songs [login to view URL] in the shop (for products chosen by shop owner) - Top level: [login to view URL] as medium level [login to view URL] to order special things in the shop for free [login to view URL] songs without protection The user pays with CC or Paypal. Https is needed. Regards Robert
