I already have a Laravel site with products in place; what’s missing is a smooth, secure path from “Add to Cart” through to order confirmation. I need you to build out the complete shopping cart and checkout flow and wire it into the existing code-base. Here’s what I expect to receive: • Fully-functional cart logic that updates quantities, taxes, discounts and totals in real time. • A checkout screen that collects billing / shipping details, validates them, and processes payment. • Payment gateway integration that meets PCI requirements—Stripe for cards, PayPal or even a bank-transfer module all work for me, so long as at least one is live and the code is written to allow others later. • Order confirmation email sent to the buyer and a notification to the admin inbox. • Clear, commented Laravel 10 code (Eloquent, Blade, Livewire or Vue—your call) plus a concise README explaining any new migrations, environment variables and test instructions. You’ll get access to the private repo and a staging server; please work via pull request so I can review commits and run test purchases before signing off the milestone. If you have solid, recent experience building Laravel checkouts, show me a live link or a short code sample when you bid and let’s get this wrapped up.
