Recreate Server version of cyberindo (QT based billing) with additional features

We need a custom billing version made by QT that should be made as similar as possible with the one here [login to view URL] Server version is what you'll need, client will be used to test on another pc later. WARNING : Do not install the client version yet, advised to use vmware for client version, server file on the other hand is safe and easy to uninstall, but client is made to be secure and will lock up the welcome screen! its meant to be difficult to remove because internet cafe requires secure billing that doesn’t get tweaked easily. The custom server then must have additional features listed here : [login to view URL] The only exception that doesn't need to be added is GCA function, The rest must be as similar as possible with the original one. And it must also be able to capture protocol from the client version. The idea here is to make a custom server version that is still able to communicate with the protocol of the old client version. 1 month testing period for bugs and features stability required. Source code is necessary upon completion
