Small Audio recorder/Playback

I'm looking for a audio recorder/playback device in the shape of a hearing aid. Few Q and A to help further explain... 1. How many audio files should this hearing aid shape audio recorder record? About 6+ audio files. 2. What is the maximum duration for an audio recording? About 5-6 mins per audio file. 3. What sort of remote control is needed? Simple RF wireless remote 4. How do I want to listen the played back audio? Through the same hearing aid using earpiece 5. What quality of sound do I expect from the device: Low data rate voice quality is fine 6. How large of a device could be acceptable? Exact size of the hearing aid: [login to view URL] 7. Battery? Non rechargeable battery such as alkaline battery, this would make it cheaper. 8. Device run time on batteries: both in standby and running conditions Which ever is better. I would like if the battery could last 4+ months. I'd like to be able to recorder information directly to the device, once finished recording, I should be able to 1) play back, 2) pause, 3) skip backward and 4) skip forward with rf remote. The device should have an on/off slide. For example: Lets say we are talking about 5 cars...Toyota, Nissan, Honda, BMW, and GMC. That would be 5 different audio files. Each containing about 6 mins worth of information. So let's say for all 5 car manufacturers I record their history, their different car models, their different colors, and their sales profits. So when I'm done listening to Toyota, I should be able to skip forward to next file which would be Nissan or if I need to listen to Toyota again I should be able to skip backward to previous file. So each manufacturer is an audio file with 4-6 mins worth of information that I can listen to. The tech is very old school I know, I just need someone to piece it together for me in the disguise of an hearing aid. That's all. I'm hoping you could take apart a hearing aid and replace the inside with an audio recorder/playback with a small external hand held rf remote. It doesn't have to look pretty. It's for personal use not for resell. I just need 1. Thanks
