IR2184, IR21844, IR2109, just some examples of half-bridge drivers. You need two of them, plus 4 mosfets, to drive a motor.
Beware: your motor is 1/4HP. That is not very much, but still enough to do some serious damage to things around, but also to itself. If you just 'put it on', without any control, it will very likely destroy itself in some time. Apply some kind of soft-start. Also, I advise you to monitor the motor current. This way you can determine wether the motor has to deliver torque, and if it's jamming or something (too much current).
