Hi, I can help you You want a clean, fast medical site that shows services, ranks high on Google, and lets patients see times and book in real time. It should be easy to update, solid on speed, and never lose data. I’ll set up the front end, connect your content system, link the booking service, and tune it so pages load fast and look great on all devices. This will take a few days, I've been doing this type of work for years. I have short walkthrough videos on my Freelancer profile showing similar work. 1) What do you have now for content, branding, and any current site or booking tool? 2) What should the final site include at launch and how should booking flow look? Ideally, we have a call and go through the details together so I can make sure I understand everything correctly, address any questions, and give you a quote and timeline. Would that work? Best, Nicolas
