Fast Typed Text Transcription

I have several pages of clearly typed, printed material that I need transcribed word-for-word into a plain .txt file. No headings, bold, or other formatting—just clean, accurate text exactly as it appears on the pages. Accuracy is the top priority, and I would like a quick turnaround. Please let me know how soon you can deliver the finished plain-text file along with a brief note on your proof-reading approach so I know the transcription has been double-checked.
