韩国采购需求：音乐盒机芯，木质音乐盒，雕刻音乐盒，婚礼回礼音乐盒，玩具音乐盒，塑料音乐盒

I'm interested in placing an order for both the 50-note and 78-note movements, starting with one of each as samples. Could you please provide me with the pricing for each movement? Additionally, I'd like to understand how the price will adjust based on varying order quantities. I'm also looking to customize the melodies to include "Canon" and "Howl's Moving Castle." Is it possible to have these specific tunes, or can we consider other custom music options as well? I appreciate your assistance and look forward to your prompt reply.
