美国采购需求：鞋类制造商、包袋制造商、自有品牌鞋类、自有品牌包袋、定制女鞋、鞋匠

I'm looking to source eco-friendly leather boat shoes in sizes ranging from 6 to 10 UK. Ideally, I'm interested in a vibrant blue color for the shoes. It's important that the materials used are sustainably sourced and meet environmental standards. Additionally, could you provide details on the production process and lead times? I'm also curious about the pricing options and any minimum order quantities that apply. If possible, samples would be appreciated, as I'd like to evaluate the quality before making bulk purchases. Looking forward to your response!
