Formal Spanish Voiceover for eLearning

I'm looking for a professional Spanish-speaking female voiceover artist to record audio for an eLearning course aimed at the general public. The course is of the 'other' category, and requires a formal tone.

Ideal skills and experience:
- Native Spanish speaker
- Experience in eLearning voiceover projects
- Ability to convey a formal tone clearly and engagingly
- High-quality recording equipment
- Reliability and professionalism in meeting deadlines

Please provide samples of previous work in your proposal.
