Express Parcel delivery to China - Parcels Packages

How much would it cost to send an express parcel delivery to China? I will ship the parcel from Peru and the package is already packed and the shipping label is attached to the box. It is a return that will be delivered to the manufacturer in Shanghai, China. The item is defective, but I will buy insurance on the shipment for the peace of mind in returning it.

What I need from your company is a pickup, a delivery, and a guarantee that you will deliver the package on time and undamaged. Would this be an issue with your company? When can you deliver this parcel to China? I would prefer the delivery be by the middle of next week if possible.

Although this particular shipment is a return and already has a shipping label attached, I would like to have access to your services in the future. Would you leave your contact info with me so I can contact you with any future needs that I may have? Thank you for answering my questions.
