All I did was go straight to the standard RES site in Asellus Prime (I took the Horizon's start) and follow the police around until I made about 1.2 million in bounties (took about an hour). After that, I was able to upgrade the FSD on the sidewinder to A class AND put DSS in one of the optional slots. After that, I mapped the Earthlikes in 2 or 3 nearby systems and accumulated (but not able to cash in yet) 2.9 million in exploration data. Then I set course straight for Diaguandri to buy a Viper Mk III for discounted prices. I explored every system on the way there and mapped several earth-like, water worlds, and terraform candidates. By the time I reached Diaguandri, I had enough to buy a fully A rated Cobra MK II, a fully A-rated Viper Mk III, and still have 3-6 million left over. I also shot up in exploration ranks to trailblazer.
At this point, I'd already met the requirements for Felicity Farseer and Tod "The Blaster" McQuinn. So I immediately took my A-rated Cobra (purchased at a nearby system for 15% discounted, and then outfitted in Diaguandri) to a location for Barnacles listed in the Codex. The trip there and then the stop of at Maia to sell the excess Meta Alloys I didn't need (had five, only need one) generated even more exploration money (now a Pathfinder). Then the trip back to Felicity generated even more exploration money, which I cashed in with her (after giving her the Meta Alloy) and shot her up to Rank 3 immediately.
Since then, I've taken off for Dav's hope to farm for mats. By the time I get back, I'll have even more cash. I'm not even going to use my Viper - I'll just let it sit there and look pretty - and will equip a DBS for my combat needs and use the Cobra for everything else. I'll just keep wandering around, making money, while gathering engineering mats/data, until I have everything I need to buy a Chieftain and engineer it. Oh... and I need to go out to the Guardian sites in my Cobra, so I can get Guardian FSD boosters and Shield Reinforcements.
Honestly, with all my traveling around for the engineers, I'm raking in so much money I have no need to transfer it from another account! I could. But where is the fun in that?
