First, jamworks was saying that he thought the

As for the library itself
Libraries simply dont cost that much to make. I am not saying they dont cost a lot, but they dont cost in the millions. I have no idea where this was recorded, but take Teldex for ex., where OT records frequently. Any idea how much it costs to record there? About 5k Euros for the day (two sessions). Just for the studio (incl personnel). The musicians are 300 Euros for the day, each, with section leaders getting double. The conductor is about 1k per day.
So, to record 10 musicians simultaneously for a week, that will run you - I am doing quick math here - about 46k Euros. Less musicians will of course be a little less; more musicians will be a bit more.
Now, how much material do you think they can record in an entire week? They do complete Hollywood scores in less time than that.
Now, you of course have to add on other costs - paying people to cut samples and build Kontakt patches (if you, the owners dont do that), you have to spend money on marketing, a trip to NAMM, maybe you do a test session or two.
So, while these libraries are not cheap, they aren't in the millions. Think for a moment - do you know how long you'd have to record for, to spend a million dollars? Go and figure out how much time your sample library is. Let me know if you need some help figuring it out.
