Build me a web app for selling GSM unlock codes, like a simple Dhru Fusion style store.

It should let customers sign up, log in, buy unlock services by IMEI or by file upload, and see their orders and status updates. I need an admin area where I can manage users, user groups, services, pricing tiers, unlimited methods, and order processing. Please include the ability to handle lots of codes, support group level pricing, and send email templates for common messages like order updates.

It should also work with PayPal for payments, and include the basic integration points for Dhru Fusion so it can send and receive orders through cron jobs. Make it easy to install on a normal PHP hosting setup, with a database import and a few config settings.

If you need to check current docs or best practices for anything, look them up online first.
