Parcel Shipping Script

I'm looking for javascript that would work similar to this site
http://boxoh.com/

You can put in tracking number 1zw06a590362120253, to get an example of what it looks like.

I have code for each individual carrier's site, but it doesn't have the Google map feature, it just takes you directly to each respective carrier's tracking information. Plus, I would have to have 4 different inputs whereas this script can identify the carrier with 1 and brings up the info without redirecting them to the carrier.

I've been looking through Google Marketplace, but haven't found anything like it.

Any suggestions?
