Custom RTC PCB Design

I'm seeking an experienced electronics hardware designer to create a compact, reliable, and manufacturable Real-Time Clock (RTC) PCB for our product.

Key Features Required:
- RTC chip (e.g., DS1307)
- I2C communication interface
- CR2032 battery holder for backup
- 5V operating voltage
- Minimal PCB size optimized for integration
- 4-pin header for interfacing: VCC, GND, SDA, SCL

Deliverables:
- Schematic diagram (PDF + source file)
- PCB layout (Gerber files + source file)
- Bill of Materials (BOM with part numbers and footprints)
- 3D PCB model
- Design review and assistance for component sourcing if required

Skills Required:
- Electronics Circuit Design
- PCB Layout (preferably in Altium)
- Knowledge of RTC ICs and I2C protocol
- BOM Optimization for cost-effective production
