Fix Oversized WordPress Homepage (Crashes + Slow Load) — Improve Google Page Speed

Location requirement: Must be based in the United States. Estimated time: 3–5 hours. Please give your own time estimate after reviewing the site, before starting work. BACKGROUND My site's original homepage was built with its entire content stored as one giant HTML block — roughly 4.3 million characters — instead of using normal WordPress/Elementor page-building. About 91% of that size is 24 photos embedded directly as base64 text inside the HTML, instead of being properly uploaded as image files. This caused: the Elementor editor failing to load or requiring Safe Mode, PHP "memory exhausted" fatal errors, 503 server errors just trying to view or edit the page, broken/overlapping layout, and slow load speed likely hurting Google search ranking and Core Web Vitals. CURRENT STATE OF THE SITE (please read before starting) The live homepage right now is a temporary, simplified replacement (WordPress page ID 2125) I had rebuilt to stop the crashing. It's stable but simpler than the original design. The original, full-design homepage still exists at WordPress page ID 653. Its content is intact but currently unlinked and should not be visited or edited without a plan — the last direct load attempt returned a 503 server error. Please don't open it in the Elementor editor without a plan, as this can trigger the same crash. WHAT I NEED — OUTCOMES, NOT A STEP-BY-STEP 1. The original homepage (page ID 653) loads reliably and quickly, no crashes or errors, keeping its original design and content. 2. That page is live as the actual homepage, replacing the temporary one (page 2125). 3. The Services, Reviews, and Contact buttons in the navigation each take visitors to the correct section of the homepage. 4. The site is fast and healthy by Google's standards — good PageSpeed Insights scores, passes Core Web Vitals, mobile-friendly. Share before/after scores. 5. Please also ensure basic on-page SEO fundamentals aren't broken by these fixes (meta titles, alt text, page titles). Full SEO strategy is a separate future project — not in scope here. 6. Any other pages with the same underlying issue are identified and fixed, or flagged with a recommendation. 7. Nothing else on the site breaks — in particular, ~35 actively-maintained neighborhood/service pages should be untouched. ACCESS PROVIDED WordPress admin, SSH/WP-CLI, phpMyAdmin/direct database access, and hosting backups (UpdraftPlus + host-level automatic backups). A NOTE ON CAUTION This site has proven fragile to edit — please take a full backup before making changes, and use staging if your workflow supports it. I'd rather this take slightly longer than risk another outage. ADDITIONAL SCOPE — GOOGLE SEARCH CONSOLE FINDINGS Please also fold the following into scope: - 15 pages blocked with a 403 (access forbidden) error - 72 pages "discovered but not indexed" — more than double actual page count, suggesting duplicate or broken URLs - Some pages with redirect errors and 404s Before starting any work, please do a full review of the site (Search Console, the pages, the server) and provide one complete list of everything found that needs fixing, along with a time/cost estimate for the whole scope.
