Break large mp3 files into several smaller mp3 files

I have four MP3 files, approx 5 or 6 mins in total. These are voice audio files that list various statistics, eg 80% of Pinterest users are women etc. I need the files broken up by sentence into many smaller mp3 files, the files named and numbered and the name and number written in a text file along with the content of the audio. (I will provide the transcript of the audio so you can cut and paste) So for example "[login to view URL]" will correspond to a text file that that contains " [login to view URL] - 80% of Pinterest users are women" etc. This is an urgent project. I need delivery by 5 PM (GMT) June 7th. Do not bid if you cannot deliver by this deadline.
