We highly recommend Click Courier (ClickBox) for courier services from the United States to Ecuador.
We have used them to ship directly to our home here in Cuenca several times.
They have reasonable pricing and their customer service is top notch.
All you need to do is send your purchases or goods to their Miami, FL. address and they do the rest. They ship every Friday from Miami to Quito and then onto other destinations in Ecuador.
