Then there are two key parameters here.
The first is the maximum torque, which in this case is (30 lbs)*(wheel radius). If you have a more advanced block and tackle pulley, you can divide by the mechanical advantage. For example, if no mechanical advantage and a 3" radius wheel, you need a motor rated for 8 ft-lbs. Not hard for a decent motor, but beyond a 'RC car' motor.
The second is a mechanism that can hold on to torque. Most motors either turn or burn. So you need a ratchet mechanism and controls to stop and start the motor when it can turn.

Depending on how much money you are willing to put into it, you could just get an electric hoist/cable wench with a remote control for under 100 bucks.
