美国采购需求：PBT材质键帽、ABS材质键帽、CSA高度键帽、Cherry高度键帽、光学开关、机械开关

I'm currently working with a customer who is looking to design a custom double shot keycap set for his specific keyboard model. The idea is to create a vibrant multi-color gradient set that includes side printing for enhanced visibility and style. This design is aimed to be both visually appealing and functional. For this particular project, I'm only in need of one complete set of keycaps. If your factory has experience with similar designs, I'd appreciate any recommendations you might have regarding materials, potential color options, and pricing. Additionally, if you could provide a timeline for the production and delivery, that would be fantastic. Looking forward to your insights!
