Stepper Motor/ Controller combination

I am in the process of building a device for a photobooth project. A rotating overhead turntable.

I would like to know the: stepper motor/controller recommended combination for this rotating overhead turntable project.
That can be capable to be connected to an Arduino and then further on be activated by a photobooth application at the time of the photo.

Capable of moving a small Logitech 920 camera held on a metal arm, supported from above.

To rotate 360 degrees. It would be something similar to those 360 photobooths, but supported from above by an arm.

But, for now I am interested in building the initial platform that can rotate the camera around the person.

Any help will be greatly appreciated.
