you either find a starting money mod, or or or...get this...You play the game and earn your way to the ship. And not to be sarcastic HOWEVER its generally not that hard to make 500K in the game. Just go from sector to sector finding large sell-able asteroids and you'll have 500K by like the 3rd or 4th. Genuinely takes less then 10 min EVEN WITH THE STARTER DRONE.

and how do you start the game with 439 097 money?
