Replicate Existing Business Website with Microsoft Entra ID Setup

I need assistance in replicating my existing business website onto a new domain. The project involves setting up the website and ensuring it is integrated with Microsoft Entra ID. Once completed, I require full access to the domain and servers. The SSO login setup will be handled separately by me. The ideal freelancer should have experience in website development, domain management, and familiarity with Microsoft Entra ID.
