Build a Jewellery Website

-Want to build a relatively fine jewelery website. Similar to https://shayjewelry.com/ - We want to start with 100 SKUs/designs initially
-Very sleek, modern and top quality functioning website. Have to be both desktop and also mobile format. Logo is attached.
- Want to receive a proposal containing specific information of things to consider for website development, data, post purchase process, offer automations, lead database etc (all details for building a premium website from A to Z)

Thank you.
