Make website for me

We are looking to develop a fully functional ecommerce website that will allow us to sell our products online. The website should have a clean and professional design, be easy to navigate, and offer a smooth user experience. It should have the following features:

1. User registration and login functionality
2. Product categories and subcategories
3. Product pages with descriptions, images, and pricing
4. Shopping cart and checkout process with secure payment gateway integration
5. Order management system for tracking and fulfilling orders
6. Customer account management with order history and wish list
7. Search functionality to find products easily
8. Social media integration to share products on social media platforms

The website should also be optimized for search engines and be responsive, meaning it should work on all devices, including desktops, laptops, tablets, and mobile phones. Additionally, it should be built on a scalable platform that allows for future growth and expansion.

We are open to suggestions and recommendations from the developer to ensure that the website meets our specific needs and requirements. Please provide a detailed proposal that includes timelines, milestones, and pricing for the development of this ecommerce website.
