Help choose motor, encoder and slew bearing for 2 axis rotary stage

I need to build a projector positionner.

It need to move +- 180° on both axis.

I do not need to help design the machine. I just need help choosing the right components to achieve the desired performance.

Please look at this video [login to view URL]

I need you to help choose the components to achieve this kind of machine but to move a light projector weighting 100kg.

I need the to achieve :

+- 180° on both axis

Maximum 30 seconds to achieve 180°

Precision < 0.01°

Repeatability < 0.01°

Needs to stay stable in any position

No "wiggle" in bearing

Parts I need to me chosen :

Stepper motor

Encoder

Slew Drive (It will be this model : SE7 see specs in attach.)

Thank you
