Responsive eCommerce website needed in wordoress

I need a responsive eCommerce website with a clean UI that works smoothly across all devices.
u hsould have demo server to work live -

I only need you to design the website and add 5–6 products (which I will provide). I will handle the rest myself, but I may need some guidance from you.

The website should include:

User login functionality
Order tracking system
Contact form

I will manage the back-end and payment integration myself. When a customer adds products to the cart and proceeds to checkout, I will integrate Stripe for payment processing.
NOTE- pls put ur real cost only - we looking developer for long time business relation so full time freelancer will b required
