iPhone fairly simple, record voice to WAV, send and receive

I would like to have the following app created. i) records the users voice to a WAV file. If iPhone cannot do wav then I will have to convert is at the server end but prefer it to be at the iPhone end ii) get the iPhones IMEI iii) encrypts (AES256) the wav and UUID and and sends that to a web site. These two files could be zipped first before sending. The web site will receive and do something with that sent file and send a response to the iPhone app. ** I already have the web side app. iv) receive the response from the web site (decrypt and display on screen) That is all. However, associated with the above there needs to be user Buttons such as ; - Start - starts the recording process. Some on screen display such as a progress bar and peak bar preferably. Progress for 10 seconds, peak showing volume of recording. - Play - enable playback of recording - Retry - go back to Start so they can record a new one to replace current - Send - actions the encryption and send process. Waits for the response (message if no connection made, timeout) (receive response from server and display message) - Exit - close app. I'm looking at as little expense as possible please as this is primarily a test because if this works it will be part of a bigger project to follow. I have an existing iPhone Dev account. thanks
