I'm looking to develop a dynamic webpage for my customers to give them progress report of their project.

Here is brief request:

1) Customer sends me an order
2) I'll send them unique URL linked to my website
3) When they click on this link they should be able to see how their job is progressing. Something similar to Dell, when you order from them you can see detail report like "order received", "assembling" "Shipping now" etc.

Could someone please help me how can we do it on the fly something like wiki software. I can do simple web designing but not sure what's the best and quickest way to do this task, assuming I have to update 15-20 customer's database everyday.

Could someone please help me where to start with I'm almost lost.....

Thanks in advance.
