Shopify Existing Domain Transfer

I need assistance with transferring an existing domain to Shopify. The domain I own is currently not connected to any other platform, making the transfer straightforward. I have full access to the domain registrar's dashboard where my domain is registered, which will further streamline the process. The ideal freelancer for this task should be well-versed in domain management and Shopify integration, demonstrating a breadth of experience in data migration involving domain transfers. Skills in troubleshooting any potential issues during or after the domain transfer to Shopify are also necessitated for a smooth transition. I currently have a domain through squarespace and need to properly link this to shopify. If someone could get on a zoom call or something and show me that would be best.
