Need to create Container Tracking Search Engine web application

We want an application, we are interested in tracking containers.

Please let us explain you the concept.

Container numbers have the format XXXU1234567 (4 letters, 7 numbers)

There are about 100 container shipping lines which own (or rent) containers.

Habitually the four letters (it is called prefix) in the beginning of the container number indicates the shipping line (or the company that rents the containers to shipping line), for example:

1) MSC Shipping Line, usually has a prefix of: MSCU
2) Maersk Line, usually has a prefix of MRKU
3) Zim Line, usually has a prefix of ZIMU
4) Hapag Lloyd Line, habitually has a prefix of HLCU and so on

All these container shipping lines have their own tracking systems which they update in daily basis.

We need to build an application where the user can enter a container number in a form, and then the application will check in the tracking systems of the company

Desired Skills are AJAX, ASP.NET, PHP, jQuery, Google Maps
