Cheap Transcription Needed (11h 50 minutes of audio) - Quality Less Important

I need a transcription of a range of 59 audio files that together add up to about 11 hours and 50 minutes of clear audio. The audios are in clear United States English. Each audio had one person talking. I need the transcription delivered in Microsoft Word or RTF format. I'd like a separate document for each separate audio file, or at least a clear specification for which transcription part pertains to which audio file. *Please Note*: - The material is proprietary, so I can't just post the audios here. I'll send them after acceptance of the project. If you want a sample to get a feel for the quality of the audio, please let me know. - Another important thing is that the transcription will be for personal use, so quality is not my #1 criterion for selection. Most important for me for this particular project is low cost. So chances are that I'll go for the cheapest bidder on this one. (Of course I do expect reasonable quality in the sense that the transcription actually makes sense and corresponds with the spoken words. But that speaks for itself.) Thanks much and looking forward to hearing from you!
