Bulgarian Voiceover for E-Learning

I'm seeking a professional Bulgarian voiceover artist for an e-learning project aimed at adults. The tone of the voiceover needs to be formal, as it suits the instructional nature of the content.

Ideal candidates should have:
- A deep understanding of the Bulgarian language with clear pronunciation
- Previous experience in voiceover work for e-learning content
- Ability to convey a formal tone without sounding robotic
- High-quality recording equipment

Please provide samples of your previous work in your proposal.

The expected duration of the e-learning content is less than 1 hour. The preferred gender for the voiceover artist is male.
