Source for high voltage power supplies for ignition

[BigBang J]

Hello, I am looking for a good ignition source for my hybrid gun. For my first hybrid I used a stun gun rated at 950,000v. Which was way overkill,
not to mention the dificulties with insulation. So now I am looking for something like stun gun electronics but at something like 50kv, the good thing about stun guns is the low voltage input, the one I had ran from 3.6v input, so I was able to use a lithium cell phone battery to power it.

Any suggestions guys?
