Audios Needed for mobile apps for training kids

This project has been re-posted. I need around 500 or more audio files for teaching small kids about basic alphabets, numbers, animals etc for mobile applications. The app is mainly used for training kids. Hence the way the alphabet or any word is pronounced, should be very clear and loud and appealing kids. I need the following from anyone who bids this project. 1. Provide sample audios pronouncing for A,B,C,D,E,ANT,BEAR,CAT,ONE,TWO,THREE. The sample audios should be very loud since this audios are going to be used for mobile apps. 2. What is the price for each audio? I like to know the price for each audios. Basically i will be providing the words for which the audios needed. For eg. I may ask you to give the audio for the word "Cool","Great job", etc. 3. I need the audios seperately. I mean you have to record and cut it and name the file seperatly. (eg [login to view URL], [login to view URL],[login to view URL]) 4. The project goes for 45 days. This means you will be having regular work from me. 5. The payment will be done partly as the audios gets completed. If you have completed 50 or 100 audios and want the money, then you can request it. Please dont bid this project if you can not provide me the above information. Thanks
