Haven't been
True, but well, there are a LOT of carriers being used to transport goods - and for those of us that don't have a carrier and have limited resources to transport goods (240t cargo bay here) ... well I will frankly be lucky to even hit the 75% mark. I am one of the people that need the permit and trying to get it. I was also running a little bit of the combat bonds one which doing only a few CZs, was able to hit the 50%-mark last night (I'm sure it will drop soon, as I'm focusing on the trade).
The money is really nice on the profit - or it was when I was able to even obtain the trade items. Now, I am spending more time scrounging for scraps to even get a full 240t of items. FCs are the bane of my existence with these types of CGs, even for those of us trying to get the end goal item out of it - a permit. Completely frustrating.
There are a few carrier owners who would help you out if you do the loading/unloading. On the other hand, there's still more than ample Cobalt to be had (~5 million tons) at bottom price at Aonikenk, 40 and a bit ly off
Wakanda Wandrama.
If you don't want to go that far and are in it for the permit (or the story, or whatever), I have a carrier loaded with 12800 tons of Cobalt a short jump over at Burigpa B (Wandrama was filled up yesterday). As I'm only in it for the money (haven't even signed up for the CG and won't), I'll log in and set it for sale at 30k/ton (or whatever, at or slightly below the CG price, so you won't make a loss - but also won't gain much. Ferengi rules.). Give me 20 minutes, I'll update here (also in case I can get a reasonable slot in Wandrama).
Carrier is

Edit: Done. Carrier is open for business. 12,800 tons of Cobalt at 30,002 Cr/t at Burigpa B , roughly 10 ls from the jump point. I get the money, you get the permit
