美国采购需求：豪华音乐机芯，弹簧驱动微型音乐机芯，标准18音符，标准18音符音乐机芯

I'm an artist exploring the creation of custom music boxes for my small business and I'm interested in getting a quote for a specific music box movement. I'm looking for a standard 18-note wind-up movement in an antique finish. Additionally, I'd like to know if there's a minimum order quantity, as I'm based in the USA. Could you also provide a quote for 25 units of the same song? And do you happen to have a song list available for this type of movement? Any details you can share would be super helpful as I work on this project. Thanks in advance for your assistance!
