SEO & Homepage Revamp for Clinic

I have a WordPress site for my dental-and-skin clinic and I’d like to give it two quick yet impactful upgrades.

First, I need solid on-page SEO that helps me climb the rankings. Your work should centre on:
• Thorough keyword integration for “Dental services” and “Skin treatments” across titles, meta descriptions, headers, and image alt text.
• Clean URL structure, internal-link tweaks, and an XML sitemap so Google can crawl us without friction.
• Basic technical checks—speed optimisation, mobile friendliness, and indexing fixes—plus a short report outlining what was done and any next steps I could tackle later.

Second, I want a modern, sleek homepage refresh that keeps my existing colour palette intact. Using WordPress (no theme change necessary), please:
• Re-arrange sections for better service emphasis.
• Add compelling hero imagery and concise copy blocks for both dental and skin offerings.
• Ensure the layout is responsive and loads fast.

I’m looking for a concise turnaround with clear before/after evidence—screenshots or a staging link work fine. If you’ve handled similar healthcare sites, feel free to mention them.
