法国采购需求：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 looking to purchase around 20 pieces of musical movements with springs for an upcoming show that features a sonorous installation. Specifically, I'm interested in having about 8 to 10 of these movements tuned to the note G, ideally covering a range of 2 octaves. Could you please confirm if this is feasible? Also, I would appreciate it if you could provide me with a detailed cost estimate for this order. Your prompt response would be greatly appreciated as I am eager to move forward with this project. Thank you!
