Need quick help with WordPress EduMall theme setup

mysiddhaschool.com currently runs on the EduMall theme, but our focus has shifted from being an online school to acting as a home-tutor aggregator. I need someone to replace the existing look and feel with the Eduall theme shown in this preview:
https://preview.themeforest.net/item/eduall-education-lms-tutors-online-course-wordpress-theme/full_screen_preview/56781508

Here’s what I’m after:
• Install and activate the Eduall theme (and its required plugins) on the live site or a staging clone first, whichever is safer for rollout.
• Re-create our key pages—especially the homepage—so they mirror the layout, typography, and modern styling of the preview while preserving our branding, colours, and existing course/tutor data.
• Adjust menus, header, and footer so visitors immediately see us as a tutor-matching platform rather than an online school.
• Keep all current content, enrolment records, and SEO settings intact; no broken links after the switch.
• Test responsiveness, page-load speed, and LMS functions before going live, then push the finished design back to production with minimal downtime.

If you’ve migrated WordPress LMS sites or customised Tutor LMS/LearnPress themes before, let me know along with a realistic turnaround time.
