英国采购需求：压花布、压花染色布、布料、素色染色布、素色涤纶布、涤纶布

I'm looking to purchase some African Pro Holland Wax Prints and would appreciate a detailed quotation. I'm interested in ordering 100 pieces, each with a length of 12 yards. The material should be 100% high-quality cotton wax print, and I'm open to mixed designs, so please confirm what's available. Ideally, I'd like the finishing to be in the Pro Holland style. Could you provide the unit price and the total cost for an order of 50 pieces? Additionally, please share your payment terms, estimated shipping costs, and delivery time to my location. Lastly, do you offer samples before I make a bulk order? Please get back to me with these details so I can move forward with my order.
