A female US voice artist is needed for use in iPad game for kids.

I need about 200 simple words as well as US alphabet to be voiced by a US native actor and recorded using a high-quality audio recording device. This is for a educational game I currently develop and since the game is intended for really young students, these things should not sound scaring or too energetic - just something motherly... If you could give me a sample of your previous similar recordings, that would be a big plus
