Real-time scraper for recado.ch – detect early car listings

I'm looking for a developer to build a Windows-based tool that monitors **recado.ch** for new car listings every 5 seconds – ideally detecting them **before they are visible on the public website**.

This is **Phase 1** of a larger project. If successful, further work (GUI, automation, OCR, etc.) will be offered long-term.

### ✅ Phase 1 Requirements:
- Real-time scraping (every 5 seconds)
- Detect listings before public visibility (via hidden endpoints or feed)
- Display:
- Title
- Year
- Mileage
- Start price + Buy-now price
- Extracted phone number (from listing text)
- Timestamps: when published & when detected
- Play notification sound when a new listing is found
- Output can be simple (text or basic window)

### ⚙️ Tech stack:
- Python for logic & scraping
- Lightweight output (CLI or minimal GUI)
- No frameworks required at this stage
