Express Parcel delivery to Costa Rica - Parcels Packages

Are there any companies who provide express parcel delivery to Costa Rica? If so, can you also arrange for an express parcel delivery that originates from Dallas, Texas, in the United States? My sister is working with a group of missionaries that are helping a group of orphanages there in Costa Rica. She has asked me to send her a parcel that includes an assortment of first aid supplies. If I do ship this parcel with your company, can you assure me that only my sister will receive this parcel? Can you also guarantee you will delivery this parcel by the end of next week?

How much will you charge me to ship this parcel with your company? The parcel is 3 ft by 3 ft by 2 ft in dimensions and weighs less than 9 pounds. Is that too large for you to ship by the express shipping methods? Also, if the parcel is damaged during shipping, will your company make good by replacing the parcel's contents? She really needs these supplies which is why I asked.

Thank you for emailing me with this information.
