[Star Wars] Where the hell did the First Order get its resources to build that ginormous Death Star knock-off?

You would think SIS would have found out about not only about the First Order, but prevent them from building one and caught off their magic income!

Well, to be fair, the planet itself wasn't constructed, and it isn't totally hollowed out.

Sure, there are a whole lot of resources that would be required to construct the "weapon-y bits" of Starkiller, but not so much that it would be unfeasible, especially in a galaxy where you can build two moon-sized space stations relatively quickly in secret. 

As for finding it, that would also be very difficult given that it was being constructed in the Unknown Regions, which is basically just a giant, mostly empty patch of space that has remained almost totally unexplored.
