Online Grocery Website Development

We are inviting experienced freelance web designers/developers to submit a proposal for the design and development of an online grocery website.
The platform will initially support approximately 500 products and must be designed to scale up to 1,000 products as the business grows. The website should be modern, fast, and easy to use across desktop and mobile devices.
In terms of look, feel, and user experience, we are seeking a design similar in style and functionality to www.bigtrolley.com.au, while remaining original and tailored to our brand and business requirements.
