Containerized Ocean cargo to Argentina

I own and operate a small materials supply company just outside of Mexico City, Mexico. I am completing an order that will be ready to ship by the end of next week. I am here today to ask for information about containerized ocean cargo to Argentina. If your company can complete this shipment, please send me your company's information as soon as possible. To complete this shipment, I will need your company to supply a 45 ft container for my employees to load. The weight of the cargo will be 18 metric tonnes. Is it possible for you to include an estimate of the shipping charge to us for this shipment? Can you also include an estimate of when you will deliver this cargo to Argentina? Does your company also agree to the customs documentation that will be provided to you at the time of shipping? Will you notify us if the shipment is delayed at customs? We will appreciate your prompt response to this inquiry. Thank you for sending it.
