意大利采购需求：精装益智书，儿童故事书，高品质设计，儿童益智故事书，互动故事书，教育益智书

I'm looking to get a quote for printing a children's friendship fill-in book. Here are the specs: 21 × 21 cm format, 26 pages (full color, double-sided), hardcover with matte lamination, and either perfect binding or thread sewing. Ideally, I'd like to use paper that's suitable for writing and drawing, around 150g/m². Please provide prices for quantities of 50, 100, 250, and 500 copies, including shipping to 73048 Nardò, Italy. I'm also interested to know about getting a sample copy or print proof, your production and delivery time after print approval, payment terms, and any specific file requirements for printing. Thanks!
