Forgetting motor type for the moment, you need to give us numbers.
How fast? How much mass must be moved? The inertia of the assembly? Required acceleration?
Once you know this, then you'll know how much power is needed to move the object. At that time you can start searching motor databooks to find one that's suitable.
And then don't forget you'll want to figure out how precise the motion must be (how much overshoot/undershoot is permissible?) so you can start with the electronic/control system design.
