We need to setup a component for joomla that grant access to a single user/client at his frontend reserved page.
It should work in this way:
Client A login into frontend joomla site and is redirected to Client A reserved page, where he can read and download content. He can't access other clients reserved page.
Client B login into frontend joomla site and is redirected to Client B reserved page, where he can read and download content. He can't access other clients reserved page.
...
Of course, site has other public content, accessible for all (user and not).
Reserved content must be not available for internal search (of course).
All the reserved contents will be managed by Admin only.

We don't want to hack any core files. Component/plugin must have an xml language file so we can translate it (in italian). We need it as a install zip file so we can install it on other site if client change domain/provider/server.
This site uses JoomFish.

We need to see a full demo before to buy.

Best regards
