Your Supply voltage is determined by the Output Voltage Swing that you need. And I Don't really Recommend 30 Volts.
The Output voltage swing will Typically be about 1 volt less than the supply voltage, but this also depends on your collector resistor.
The Current will partly be a Function of the Collector Resistor and Emitter resistor.
If you are going for Voltage Gain, I would recommend a 2K2 to 10K on the Collector.
An Emitter resistor will help with bias as well as protect the transistor from excessive current. (Possibly a 470 to 1K resistor)
Bypassing this resistor with a Capacitor, will help with Low Frequency Response. (.1uF to 100uF)
This Info is Very General.
If you need more info, I would suggest you do some Research, or a lot of expermenting.
