Looking for a Good Mock Solar System

We have been doing Apologia Astronomy and I would like to get a mock Solar System. Not just one of the ones made out of Styrofoam balls, but one where the planets actually turn around the earth so I can show them how the earth rotates and revolves. Does anyone know where I can buy something like this or possibly make one. I would also like for the earth to be able to tilt showing how the seasons change.

thanks
