Hi, I've been designing and developing database solutions for over 7 years. Simple tracking system, would need few steps
1. Create an ID for consignment - you stick it to the consignment .
2. Named points where consignment is monitored ( sent, delivered, some intermediary points )
and probably quite few stats and admin tables.
I bid on test project only. I can make very simple working prototype for you.
The proper project needs preparation, case study etc .
