I'd let him have it, and only apply the highest reduction, not multiply or add them.
So at best, a 30% reduction in base costs, and if you're feeling stingy, then don't reduce the XP cost. Item creation is annoying anyhow, so giving him some advantage is OK. On the other hand, adding reductions like he suggests - that is crazy.
And the resale value I'd just estimate depending on the NPC buying it. It might be completely worthless anyhow.
