Need schematics for DC-HV converter 800w ?

Hi all, I'm building a coilgun, and I need a inverter that charges my 360J in 1 second or less. The voltage is 800v and requested current is 500mA or more. I know that such system wouldn't be so portable but, I plan using 12~24v (8x18650 - or RC model batteries, both flucutates between 25,6v and 33,6v).
Anyone that could lead me to the right direction or post schematics/websites that could help would be appreciated. Thanks all!

oh by the way it is 400w, not 800w.
