Website Hosting and Website Builders

I am looking for an easy DIY website host/builder to move my website. We are currently on TherapySites with Stripe service and although the all-in-one website model was what we wanted, we are not happy. Any recommendations?
Wanted: DIY Website builder, HIPAA compliant, SEO capabilities, easy navigation/editing, able to embed portal, billing and scheduling, perhaps even create superbills and more. Does anyone have any recommendations? Thanks.
