How to get 450000 money?

[FireAgostini]

So, I am at that Gustav quest where a certain person asks for this amount of money. I have my boat with only 2 upgrades missing (last speed and last size) but I am no where near having that amount of cash. I am sitting at 80000 right now, any tips on how to get fast money?

You don't need the money; go back to Oxbury and speak with the ex-girlfriend at the Cafe
