Need to drive a DC motor!

I have a request, it's
urgent, cause my undergrad project depends on it. (So,
please reply fast). :(
I am working on a project in robotics and my
branch is Computer Science. I require a circuit idea
for controlling a 12V, 500mA DC servo motor. I am
reusing a receiver circuit of an RC toy car. Which
provides me with two terminals with voltage varying
between +4.5,0,-4.5 volts.( The two terminals provide
positve voltage with respect to common ground)
All I need is to drive the Servo motor, with direction control provided by the two terminals and common ground, without any
form of speed control or braking. I am using a 12v
lead acid battery for the servo and AA size batteries
for the RC circuit. If you need any further
information, please mail me on this address.

Waiting for a reply,
Regards,
Ashish Narain

P.S. I am not using any PWM signal, just driving the servo as any other DC motor (using it mainly for the high torque).
