I'm like duuude it's really not that hard to get on an AMI/MD team with guild/randoms is it?
OK I have yet another suggestion for you. You make around 500g/allod in S3 just from the non-upgrader loot you get and the gold for killing the 4 bosses. If you have alchemy as a profession or loot an epic chest then you make far more.
What this means is that you only need 1 other person in your party to hire 2 mercs each and you will break even on your runs as well as looting parts and crystals. It's not hard to fly in S3 even with the basic gen 9 ship and so long as the merc-monkey you picked up is fixing the shields, you'll be fine.
Yes, you will have to unlock the shop to buy the gen 11 crystals there. You can do this via AMI or the Control of Trade quest. Again, ask in guild or Novo/Nezeb for parties. Good luck, adios, chachacha.
P.s. Hope this was helpful and not just a pain in the butt cos you were trying to push your idea for crystals and parts from Wellebell loot
