Hi!
I would be happy to work on this project for you.
I understand that you want a web application where you can manager users and their login details, and they can then input their license expiry dates. X days before expiry, the software sends a notification SMS or Email to the user (if you don't have an SMS/Email gateway, I am happy to help you set this up)
I am also located in Australia so communication is much easier - I can have the project finished ASAP, with a basic example to you tonight, and the full project completed tomorrow.
Looking forward to working with you
Thankyou,
Hayden
