I spent a little time looking into capital modules. The BPOs for these are around 100M to 300M and all require at least Capital Ship Construction to 1 in order to build. The fighters require Cap Ship Construction to level 3.

I need to stare at this a bit longer, but at first glance it means:
1) Capital modules are profitable even in Jita. Some of these modules are selling for 25% markup at high volumes in Jita. That's unheard of profit for T1 production.
2) Volumes are low everywhere bit Jita/The Forge region. Even Rens isn't a great place to buy/sell these things. We wouldn't want to stick this stuff up on the Derelik marketplace without doing something more. We could package module up with ships or sell them the same place we deliver capital ships.
3) Fighters are lower profit, but higher volume. They don't sell that well in Derelik, but if we chose the right place and sold them for just above Jita price we could make a 25% profit there as well. Could someone check to see what they're selling for deeper in Providence?

I already have the Firbolg and Templar BPOs researched to ME40
