Membership Site to Sell Unique/Custom Articles or Proxies

I am planning to sell some unique data information to each member signed up through s2member that can be accessed immediately after someone becomes a paid member.

Lets suppose I am planning to sell unique "Ready-Made" articles to my member... I have thousands of "ready-made" unique articles uploaded on my secured server.

A paid member when signup should automatically be able to download list of the files or the data can be shown inline on the page which is supposed to be the DASHBOARD (after loggin). That file once accessed should not be available to be accessed by any future member. Any new member added should always have access to the files NOT accessed by members before.

Let me know if it is possible through S2Member or any other membership plugin?

OR

I want to sell list of PRIVATE PROXIES using simple membership. Its all setup and ready to be used! Each member should have access to 10-100 proxies depending upon his suscription level. I just want immediate download or access of the product information that should be unique to each member.

Please reply asap.

I hope you find a solution for that, as i want to sell something like that via membership site!
thanks

Why don't think to start you own PLR membership site to sell your articles? The entire process is available at another forum. Pm me, I'll provide you the guidance.
