WordPress malware removal and Elementor Pro replacement, urgent fix needed.

We have a WordPress website that's been compromised with malicious JavaScript injections and a suspected rogue plugin persistence mechanism. We need someone experienced in WordPress security to do a full website backup before starting, remove all malicious JavaScript injections and unauthorized code across theme and plugin files, remove a suspicious persistence mechanism found in a rogue must-use plugin, clean the WordPress database of any malicious entries, remove an unofficial cracked version of Elementor Pro and replace it with the official licensed version, update all outdated plugins and themes, fix any layout or functionality issues that result from the plugin replacement, and rescan the site afterward to confirm it's fully clean. We have a security assessment report available with the full technical findings, happy to share with serious applicants. Looking for someone with strong WordPress security and malware remediation experience who can work efficiently and turn this around quickly.
