n8n Automation & Form Interface

My goal is to take an existing n8n workflow (initial draft already produced by Claude and accompanied by a written spec) and turn it into a polished automation backed by a lightweight front-end where users can submit data through a form. The workflow is an MVP of a larger, more complex project to come.

Here is what I already have:
• A clear specification that walks through each step the workflow must perform.
• The first version of the n8n flow—nodes are in place but need refinement and error handling.

What I need next:
1. Tighten the n8n logic so the automation runs reliably end-to-end, with sensible retries and clean failure notifications.
2. Build a simple, responsive form-based interface (any modern stack is fine—React, Vue, Svelte, or plain HTML/JS) that lets users input data the workflow expects. No dashboards or reports are required right now, just clean data entry with basic validation.
3. Wire the form to the n8n instance—REST hooks or webhook nodes are acceptable as long as new submissions trigger the workflow without manual intervention.

Acceptance criteria
• All fields defined in the spec are present, validated, and passed to n8n exactly once per submission.
• The workflow completes without unhandled errors when fed both valid and intentionally malformed data.
• Clear setup instructions so I can deploy the form (static hosting is fine) and import your final n8n JSON on my self-hosted instance.

If you’ve shipped production n8n automations before and are comfortable spinning up quick front ends, this will be straightforward. Please mention similar work or link to a live demo in your bid, and tell me how soon you can start.
