CodeIgniter Service E-Commerce Site

I need an e-commerce website built with the CodeIgniter PHP framework that lets customers browse and purchase my professional services. The site must include a secure user registration and login system so clients can track their orders and manage their profiles.

For payments, I want PayPal fully integrated and tested in both sandbox and live modes. I may add card or bank options later, so please keep your code modular enough to plug in additional gateways without a full rewrite.

Key deliverables:
• Responsive storefront and service-detail pages
• Password-protected customer accounts with email verification and password reset
• PayPal checkout flow, order confirmation, and IPN handling
• Admin dashboard to create, edit, and deactivate services, view orders, and issue refunds
• Complete CodeIgniter project files, SQL schema, and a brief setup guide

Acceptance criteria: All core pages load error-free, user actions (register, log in, buy, view orders) work end-to-end, and a real PayPal transaction completes successfully during hand-over. Let’s keep the interface clean, the code well-commented, and the turnaround time reasonable.
