Hi I have a circuit (attached) with a 5v power supply operating a bjt allowing 12v to operate a MOSFET (TO-220 3N60P). The MOSFET completes the circuit for a motor running at 12v. The circuit may seem a little pointless, but its part of a larger circuit, and i thought this would simplify the issue. The reason im not running the mosfet at 5v is because at 12v the max drain source current is a LOT higher.
The Mosfet data sheet is at:

Using r1=470 ohms opens the bjt, however i cant find suitable values for r2 and r3 which open the mosfet. r3 is a pull down resistor allowing the mosfet to turn off again once power is cut to the gate pin.
Help would be appreciated, because I am quite stuck.
THANKYOU
