215231 a simpler version of yahoo

I need a working clone of yahoo with less features. The website must have: 1. The webmail in yahoo style - security is the main priority - spam filter must work properly - the "keep me signed-in" option must work and when the user returns his mail inbox must be displayed on the main page (like windows live at [login to view URL] does) - like yahoo we must be able to add a text ad at the bottom of every email sent by our users 2. The games section but it must contain only java games that can be played online for free 3. A working GeoIP tool so that on the main page we can display the weather forecast for our user's city 4. A small "currency rates" section on the main page 5. The Messenger is an option .. Depending on the price i will think to add this one to. Some other things must be done .. smaller things like custom designs, custom logo designs, etc.) We need to install this website on a temporary server to see how it goes for 3 months and after that we need to re-install it on a permanent server.
