Voice for Children's educational books

We are looking for experienced voice readers for children's educational books. These are 320 Red Rocket instructional readers. They are 4 sets of 8 titles at each level (32 total per level) and we want different voices - male and femaile within each level. We are looking for adult voices to model reading for children first learning to read.

Pronunciation of words must be clear and particular attention paid to the speed (slow) and phrasing/fluency. We wish to deliver these to our customers (schools) on CD’s. There are 10 different levels. The lowest level books only have 50 words. e.g 32 titles with 50 words the highest level readers have 650 words e.g. 32 titles with 650 words. There are downloadable eBooks on our website if you need a preview. Half of the books are fiction stories and the other half are non-fiction photographic topic books. [login to view URL] Thank-you!
