Copy Expert Sapiens?

Build me a SaaS web app like Expert Sapiens.

Expert Sapiens does: We offer experts in all industries to display their profile for international clients, and also have internal marketplace to purchase AI tokens for internal tools. It reportedly makes about $400/mo, so the core idea clearly has demand — I want a lean version I can run and charge for.

Start from the open-source project aimeos/aimeos (https://github.com/aimeos/aimeos) — reuse what fits, strip its branding, and build the specifics below on top of it.

Requirements:
- Nail the single core loop that Expert Sapiens is known for — build that end to end first.
- The main dashboard/workspace where users do the primary task, with sensible empty states.
- Any AI step that makes it feel modern (generate, summarize, or automate the tedious part).
- Data persistence, search/filter, and a clean history/list view.

Also:
- Clean, modern, responsive UI with a thoughtful landing page.
- Email/password auth and a simple paid tier (Stripe test mode) so it's ready to charge.
- A README covering setup, environment variables, and how to deploy.

Ship a working MVP I can run locally first, then help me deploy it.
