Buy something small with a train CD, but traders for 1 mil at a time and CD them when they don't give it to you.
Do this a few times and buy a bomber (~24million for full setup), then start pirating for 2 million a piece, if they are a 5k transport pirate them for 3 or 4 million, if they have ~3k ore then pirate them for 5 or 6 million, if they have 5k ore then pirate them for 8-10 million.
Give that a few days and you can buy a 5k transport yourself and trade ore for a battleship or cruiser. Or get a friend with a Freelancer ID'd 3k and just cargo pirate for everything you can carry and make even more in less time, try to stick around places that have high sell points for ore. 30 million per ore trader that comes by adds up fast and it's fun.
Pirate near a gate and use the lane to block it's guns, watch for lawfuls, if they're coming from your back, shoot the lane and fly through the gate and then fly up/down/left/right to run from then, return to pirating when they're gone. If they come FROM the gate, go straight through the gate as it takes them 30 seconds to go back through, fly off plain once again and return to piracy once they're gone.
