Using a flyback transformer sounds like the obvious first thing to look at.
Finding one off the shelf with the right characteristics will be the tricky
part.

Since you're a mechanical engineer and you're talking about voltages that
could easily kill, you should get someone who knows this stuff to do it.
Would you want to be hanging over a deep gorge in a cable-suspended trolly
designed by a electrical engineer with limited knowledge about mechanical
systems?
