Request assistance in a Driver Circuit

[VASANSNS]

Hello everyone,
I am trying to build a driver circuit for a CCD. The input is a clock signal from 0 to 3.3v and the output needed is from +15 to -9. I tried to simulate in Multisim with a simple Push pull BJT amplifier. I have attached the circuit screenshot. I know that the simulation is ideal and the input clock cannot bias the transistors and supply the turn on current. Hence i need some help in designing the biasing circuit for the transistors. How to Start from the Datasheets of the transistors.
Also any other suggestion is also welcomed.

Can you use a NE555 to have a try?
Choose the appropriate resistor and capacitor, pin3 will get a square-wave. It can bia the transistors in this circuit.
