Need machinest

I need someone to make me a gyroscope rotor like the attached photo. Needs to be about 5 inches in diameter and half inch thick and the center hole would fit a prop adapter (l need to get size of the adapter yet). Material could be aluminum, brass or steel. Please pm me your price. Only need a one-off but perhaps a couple more in the future.
Also attached pdf of specs.

Update: found a source to make the rotor for me for 105$.
