新加坡采购需求：和纸胶带、计划贴纸、牛皮便签、日记卡、翻领别针、金属书签

I'm interested in placing an order for a set that contains 30 pieces, each measuring 5cm x 6cm. I'm looking for the pieces to come in three specific pastel colors: blue, purple, and green. The customization is key for this order, as I'd like each stack personalized with unique names alongside some small doodles to add a creative touch. Could you please provide me with details regarding the pricing, minimum order quantities, and lead times for this customized order? Additionally, I'd appreciate information on any available options for design proofs or samples before finalizing the order. Looking forward to your prompt response!
