Restore Offline WordPress Website Quickly

My WordPress site has been completely offline for more than a week and I need it brought back online as soon as possible. No plugins, themes, or settings were knowingly changed before the outage, so I’m looking for someone who can track down the root cause, fix it, and confirm everything is stable...
