Same as for the Thanatos, but for the Orca:

Component BPCs Subtotal	33,520,000
BPC for Ship in Question	35,000,000
Mineral Cost, at Jita Prices	329,784,076
Cap Ship Total	398,304,076
Plus 10%	438,134,483

These are currently selling for 429M in Jita, 434M in Rens, and 415M on the forums. If you're willing to order 60 days in advance, one of the forum shops will sell this to you for 385M. That means you can make 10% on these in Rens.

There are a few listed for sale in Derelik starting at 450M, but very few ever change hands at that price. Five or six change hands in Derelik every week, and half of those are sold to the market by people who must be desperate to be rid of them. The ones purchased from the market go for about the same price as Rens.
