Guided Secure Website Migration

My current VPS has been compromised and I need to relocate the entire site—including all files, a MariaDB database, and its DNS server setup—to a fresh, hardened Ubuntu box. We will work side-by-side in real time over Zoom with shared screen; no unattended access will be granted... (Budget: $200 - $300 USD, Jobs: Apache, DNS, Firewall, Linux, MariaDB, System Admin, Ubuntu, vBulletin, Web Hosting)
