Build AI Voice-to-Invoice MVP (Speech to PDF via Email)

I’m looking for a UK-based developer (or small team) to build an AI-powered MVP tool that allows users to speak an invoice aloud, have it transcribed, and automatically generate and email a professional invoice PDF.

This tool is aimed at small business owners (like tradespeople, coaches, and landlords) who often delay invoicing due to time constraints.

Core workflow:
• User speaks naturally: “Invoice Bernie’s Beans for £100 for helping me clean the garden”
• System uses Whisper API (or similar) to transcribe the message
• Extracts client name, service, amount, and date
• Prompts for missing info (e.g., email, address)
• Generates a branded invoice (PDF)
• Sends the PDF to the client via email (using Gmail or SMTP)

Optional (quote separately):
• Stripe/PayPal link on invoice
• Simple dashboard of past invoices
• Save invoices to Google Sheets

Deliverables:
• Working hosted MVP (web-based or via Bubble/Glide)
• Functional flow from voice input to emailed invoice
• 1–2 invoice templates (custom branding)
• Light documentation / short walkthrough

Tech Suggestions:
• Whisper API, Otter.ai, or AssemblyAI
• Zapier/Make.com or lightweight backend
• jsPDF or Puppeteer for PDF creation
• Gmail API or SMTP for email

Please include your experience with transcription or automation projects, your proposed approach, and estimated time/cost.

Skills:
• Voice recognition
• Whisper API
• Artificial Intelligence
• Automation
• PDF generation
• Bubble.io
• Gmail API
• SaaS MVP
• Speech-to-text
