Orchids Site to WordPress theme Conversion

I am looking to migrate my current business website from the Orchids platform to a fully custom or highly tailored WordPress theme. The primary goal is a "one-to-one" rebuild. The design, content, and functionality must mirror the current site to maintain brand familiarity, but the underlying architecture should be optimized for WordPress.

Core Objectives
Exact Visual Rebuild: Recreate the current design as a lightweight, responsive WordPress theme.

Feature Parity: Rebuild contact forms, service listings, and testimonial sections with improved backend usability.

SEO Preservation: Zero loss in SEO equity. This includes a 1:1 migration of all URLs (or implementing 301 redirects), meta tags, alt text, and internal linking structures.

Performance: The final theme must be lightweight, achieve high Core Web Vitals scores, and be mobile-first.

Technical Requirements
No-Code Management: While the theme may be custom-coded, the end result must allow me to update text, images, and services via the WordPress Block Editor (Gutenberg) or Custom Post Types without touching code.

Functionality: * Contact Forms: Integrated with reliable delivery (e.g., WPForms or Gravity Forms).

Service Listings: Built using Custom Post Types for easy organization.

Testimonials: A dedicated, easy-to-manage section.

Cross-Browser Compatibility: Perfect rendering on Chrome, Safari, Edge, and mobile browsers.
