Quito courier?

Have lost a good deal of money with other couriers and am eager to find a satisfactory one. Yesterday I was told about this one. Do you have experience with the Quito courier who uses Servientrega to deliver to Cuenca, with deposit first to her bank acct. here?

How long between US deliveries to this courier and Cuenca delivery? And comparative shipping costs?
Thanks for your time and sharing.
