HIPAA Compliant Client Portal

Need a HIPAA-compliant client portal for a custom, editable checklist system for about 50 clients, starting with a pilot for 10. Each client will have a dashboard with roughly 10 of 30 total tasks, each with 1–5 subtasks. The portal must be fully customizable from our end, with different task sets for each client. I need a simple pilot build completed quickly, ideally within 48 hours. Looking for someone who can work fast and deliver a secure, editable solution for this initial phase.
