If you want to make

of money and you are somewhat of an experienced player, you have decent skills and have Caldari Battleship lvl 2, i suggest you do agent missions. Get negotiation, connections to lvl 4, and start with a lvl 2 or somthing in internal security or just security in any caldari corporation. Work you agents up to a lvl 4.
While running two chars, one in a megathron with tech 2 ownage, the other in a raven to tank the damage, i was making about 80-100mil a day, and approx 40mil on the Extravagganza missions. It can be a little rixky if you dont know what you are doing, but the potetial is out of this world.
On a side note, this is why the market has turned to **** and why battleships sell for over 120mil each. They used to be around 103-110mil.
