Looking for a Common Market to Join (Kebir Blue)

I figure it's time to get more involved and would like to join a common market on the understanding that I'm a rank amateur at it.

My main country is Nostero (lots of cash, pretty good stats, about 100 corps mostly functioning at 100%) and I just started a slave country next door, Grandab. I also have a 100+ corp enterprise, Hifeng Holdings.

I would very much appreciate any guidance and/or common-market invitations.

Thanks and be well.

Edited to add: Tax rate is 0% if that matters.

You should have received an invitation from Helms Index now. It is an promissing little index made up of a few relatively new players with prommissing economies and burgeoning empires. I hope you will join us.
