2000 oz-in and very, very, very slow rotation. Remember your limitation on servo power.

You need both speed and some power, so a servo probably isn't the device you want. You're saying a VEX motor doesn't have the power. Well, that leaves either a light Banebots or a small pneumatic cylinder. If you aren't otherwise using pneumatics, then the pneumatic cylinder is not going to help weightwise (because then you have to add a full system somewhere). That leaves a light Banebots motor (probably the RS395), or maybe some of the other lighter allowed motors.

Or... Wait, would a 1-inch throw electrical solenoid actuator work? How about a Denso throttle control motor? What about an AndyMark motor or gearmotor?
