Urgent Holiday Detector Circuit Design

I need an expert in circuit design to create a model for a Holiday Detector. The primary purpose of this detector will be identifying defects in coatings. Although the type of defects wasn't specified, proficiency in pinpointing a variety of coating defaults - from pinholes, cracks to blisters - will be advantageous. I need this project completed as soon as possible. Ideal candidates will have:

- Proven experience in circuit design
- Knowledge of defect detection in coatings
- Ability to work with strict deadlines
- Excellent problem-solving abilities.
