Mobile & Tablet Optimization for WordPress Site

I have a WordPress site designed via Elementor primarily for desktop use, and I need a designer who can optimize this for tablet and mobile viewing. The aim is to keep a concise, streamlined yet dynamic design, while ensuring that key desktop design elements are retained.

Key Priorities:
- The layout and structure of the desktop design is the highest priority to retain.

I'm looking for a reliable professional who can assist with this project, and potentially future ones, in a long-term working relationship.
