The circuit is same as that of florascent lamp used for house lighting and you can use the same choke & starter. I am using philips 9inch UV tube. I do not remember the number, If you need it I can search it for you or you can find it in their catalog. For timer, you can use any mechanical timer that works upto 30mins or make your own PIC timer! Make the case such that the processor is around 1inch away from the tube and can be easily placed.
