Ecommerce Redesign and Shopping Cart

My current website is up and running, yet it stops short of letting visitors buy anything. The focus of this update is squarely on adding full-scale e-commerce functionality, with a smooth, reliable shopping-cart flow at its heart.

Here is what I need done:
• Integrate a shopping cart that keeps items persistent across sessions, works flawlessly on mobile and desktop, and updates totals in real time.
• Re-work the existing page layouts just enough to showcase products attractively and guide users toward checkout without clutter or extra clicks.
• Connect the cart to a secure payment solution (I’m open to your recommendation) and make sure order confirmation emails fire correctly.
• Migrate or create any back-end settings required—tax, shipping, coupon logic—so I can manage them from an admin dashboard.

The rest of the look and feel can stay recognizable; think of this as a functional expansion rather than a full visual overhaul. Clean code, clear documentation, and a staging link for review are essential for hand-off. Once everything tests out end-to-end, we can schedule the go-live.
