I would like to request a quote for the logistics involved in collecting a shipment from a merchant in Guangzhou and delivering it to Singapore. The total weight of the cargo is approximately 90kg. Please provide details regarding the shipping options, estimated transit time, and costs associated with this delivery. Additionally, it would be helpful to know about any pick-up requirements or documentation needed on my end to ensure a smooth process. If there are any specific services or recommendations you can provide for this shipment, please include that information as well. Looking forward to your prompt response!
