Voice Actor for Eartraining Exercise Videos

We have 20 Videos of Eartraining Exercises that each have between 250-500 words and we are looking for an african american woman with a young voice (should sound between 20 and 40 years old) for an energetic and motivating performance (Imagine you'd be giving a Zumba class).
If you are looking for a medium sized project with fair payment contact us (please attatch an audio example) and we will find a good arrangement.
