Pre-Employment Vetting Colombia

I'm in need of a professional pre-employment vetting service for candidates in Colombia. The service should primarily focus on validating information on the employment certificates provided by the candidates.

Key Requirements:
- Validation of Employment Dates: The service should verify the accuracy of the employment dates provided in the certificate.
- Certificate Authenticity: It's crucial to ensure that the employment certificate is genuine and not forged.
- Designation Verification: The service should confirm the candidate's job title/designation with the employer.

Method of Verification:
- Direct Employer Contact: I prefer the service to reach out to the candidate's previous employer directly to verify the specified details. ( Physical Site Visit )

The ideal candidate for this project should have:
- Experience in pre-employment vetting or background checking
- Understanding of employment verification standards in Colombia
- Strong communication and negotiation skills for contacting employers directly
- Attention to detail to ensure the authenticity of the provided certificates.

Please provide details of your approach to this task and your relevant experience.
