Car Bonnet Repair

I'm seeking a skilled mechanic to help with my car bonnet that won't open. I have already tried using the release latch inside the car, and while I did hear a sound when attempting to open it, there was resistance.

Ideal skills and experience:
- Automotive repair knowledge
- Experience with car bonnet mechanisms
- Problem-solving skills
- Tools for manual intervention

Please provide a quote and estimated time for resolution.
