Enhance LivSafe Website Functionality

I currently have the basic LivSafe Home website built through Free Website Guys: https://livsafe.fwgsite.com/ The public-facing website is already established, and I am not looking for a complete website redesign. I am primarily looking for someone to add the functional client and admin side of the business while keeping the design/branding cohesive with the existing site. LivSafe Home provides private-pay home safety assessments. Clients will complete the process remotely by submitting information, completing a home safety checklist, and uploading photos/videos of their home for review. I would like to add: * A one-time payment/checkout system, preferably Stripe * A secure client login * A client dashboard/portal * A secure admin dashboard for me * Client intake form * Online home safety checklist * Room-by-room photo and video uploads * Client progress/status tracking * A way for me to review each client's information and uploads * A place for me to add private admin notes * Ability for me to upload the completed assessment/report as a PDF * Ability for each client to access/download only their own completed report The ideal customer workflow is: Current LivSafe website → Purchase Home Safety Assessment → Create/Login to Client Account → Complete Intake → Complete Home Safety Checklist → Upload Photos/Videos by Room → Submit for Review → LivSafe Reviews Submission → Completed Report Becomes Available in Client Portal. For the client dashboard, I would like the process to be visually simple and show their progress, for example: 1. Payment Complete 2. Complete Intake 3. Complete Home Safety Checklist 4. Upload Home Photos/Videos 5. Submitted for Review 6. Assessment Complete / Download Report For my admin dashboard, I would like to see all clients and quickly identify: * Payment status * Intake completion * Checklist completion * Photo/video submission status * Date submitted * Assessment status * Ready for Review * Report in Progress * Completed When I click on a client, I would like their intake information, checklist answers, photos/videos organized by room, admin notes, and final report all accessible in one place. I am open to a no-code/low-code solution such as Softr + Airtable/Softr Database + Stripe rather than building a completely custom application. Ideally, the client portal could live on something like: portal.livsafehome.com while the existing public website remains the primary marketing website. I would like the freelancer to recommend the simplest, most cost-effective setup that can accomplish this while maintaining secure individual client access and an easy-to-use admin system.
