The best advice I can give on how to get rich QUICK is to do null sec relic exploration until you have enough money to buy one ticket for a jump freighter on the hyper net. Keep doing this until you win and then sell it. Statistically you should have won before you overpaid for it. From there you have about 10bil in capital and you can start station trading which makes some of the most money in the game by far.
I recommend watching Oz Eve for trading advice.
