Create new customised Shopify store

I have an existing Shopify business and am looking to create a customised Shopify store using a new domain name. I will need contents and customer journeys from the website transferred to this new shopify store and customisation options, features and design added to make it stand out, improve functionality and make it easy for us to update, add new products and mage orders. The customisations will need to be tailored to fit our brand and business needs for optimal satisfaction. The ideal candidate for this project should have extensive experience with Shopify and customisation to ensure that all requirements are met.

Ideally someone with experience in UK websites.
Would be great if you have developed pet business based websites.

This project is highly urgent, so whoever takes on this job must be available to work quickly and efficiently.
