dc current amplifier

dc current amplifier

(OP)
I need help in creating a dc current amplifier.  The current/voltage source would be a battery.  The amplifier could be multi-staged.  I would like the output current to be in the range of 50 - 100mA, and the input current being in the range of 5 -10 mA.  It will be driving a small electric motor.  Could someone make a recommendation of what type of amplifier circuit would be best suited for my needs?  Thank you very much.
