What bracket & servos should I use for a Servo Controlled laser?

I am attempting to build a 3D Laser Scanner to scan a multitude of objects.
Precision is actually more important than accuracy.
I plan to use a line laser but the width will limit my accuracy.
I am not entirely sure the accuracy I will need since it won't be a flat plane that I am scanning.
Objects shouldn't be larger than 8x8x8in.
Distance will be somewhere around a yard depending on the focal length of the lens I use.
I imagine I need something better than hobby quality?
