American Voice Over

I'm in need of male and female voice overs with a range of American accents to create stimuli for a language experiment. The voices should convey a conversational tone. The script is 272 individual sentences (1850 words; about 15-20 minutes of audio), and I would like to pay a flat fee of $40.

Ideal Skills:
- Voice over experience
- Ability to convey a conversational tone
- American accents
- Male and Female voices

Please provide samples of your work if possible.
