wordpress website migration expert needed

I need my existing WordPress website moved from my current hosting provider to a new one. The site must look, behave, and load exactly as it does today—no design tweaks, no content edits, and no email accounts involved.

Once the migration is complete I expect:
• All pages, posts, plugins, themes, and the database running flawlessly on the new server
• Permalinks, media files, and SSL certificates intact so visitors see zero disruption
• DNS or nameserver changes handled so the switch-over is smooth and downtime kept to an absolute minimum

If you have a proven track record with cPanel or similar control panels, MySQL, and WordPress backups/restores, this task should be straightforward. Please outline your typical turnaround time and how you verify a successful hand-over before propagation.
