We are looking to implement Amazon.com-like functionality to our shipping rate calculator on our website. This means we want to combine a rate request and a time-in-transit request in order to tell customers the exact date they will receive their package. This job requires familiarity with the UPS API -- in particular we are going to use the Rocket Ship.it library to communicate with UPS. http://www.rocketship.it We want a proof of concept developed as a standalone PHP web application. Please see the detailed specifications in the attached PDF document!
