Hey folks... I really appreciate the community here and the help I've received. So I thought I'd share... (Disclaimer: This can be found out on the interwebs as well. I do not claim originality but I did this recently to get my Corvette in just 4 days)
TARGET SYSTEMS
1) Col 285 Sector YF-M c8-8 (Lebedev Installation - Planet)
2) Niu Hsing (Gorbatko Terminal - Outpost)
3) Niu Hsing (Cabrera's Claim - Planet)
GUIDE
1) Arrive at Lebedev Installation
2) Take all data courier missions to Niu Hsing (there will be missions to both Gorbatko and Carbrera's)
3) Log until you have 20 (this doesn't take long at all from Lebedev)
4) Fly to Gorbatko in Niu Hsing first (the majority of the missions from Lebedev will be turned in here)
5) Take what data courier missions you can find for Col 285 Lebedev (optional: you can log a few times if you want... but don't spend a lot of time here)
6) Fly to Cabrera's Claim (turn in the rest of the Lebedev missions)
7) Log until you have 15-20 data courier missions back to Lebedev
8) Fly back to Lebedev and turn in all missions
9) Rinse/Repeat until you've reached your goals
NOTES
1) You will need a small/medium ship with a minimum of 4t of cargo space (AspX is the perfect ship IMO w/ enough cargo to take some of the cargo missions on top of the data missions)
2) The distance between the two systems is only 12ly
3) After becoming allied at each place, the data courier missions were/are paying a ton of credits per mission (90,000-150,000). (I didn't min/max during the grind but there were times when I had 20 missions all over 100k credits each)
4) This is my goto missions location (Lebedev) when I need engineer commodities (I log until I've got enough missions for the commodities and then I stack 100k+ credit missions on top until full)
5) Over the course of my grind, I made right at 200 million credits from this alone
So there you have it... I hope this helps someone. If not, please feel free to ignore
