葡萄牙采购需求：物流、运输、海运、空运、DDU、DDP

I'm interested in getting a detailed quote for shipping costs from Portugal to Sierra Leone. Could you please provide me with the shipping rates along with any additional fees I should be aware of, such as customs duties or handling charges? Additionally, if you have different shipping options available (like standard vs. express), please include that information as well. This will help me make an informed decision based on my budget and timeline. Thanks!
