Counter Strike Source : CW-server booking system

Hey Freelancers! I need a simple booking system for one or more Couter Strike Source servers. - Users must be able to book for 2 hours. - It should only be possible to prepare three bookings at a time - Automatic restart of the server after 2 hours. (End Clan War) - Simple Login System using username and password. - Users will receive rcon password and IP per. mail 10 minutes before their booking starts. I hope somebody can help me :)
