Hindi Lecture Audio Transcription Needed

I have a series of Hindi-language lecture recordings, each running between thirty and sixty minutes, that I need transcribed word-for-word into clear, well-formatted text. Accuracy matters more to me than speed, but I would still like to keep a reasonable turnaround for each file so the material can move quickly into editing and publication.

Here’s what I’m expecting from you:

• Listen carefully to the Hindi audio and produce an exact transcription, preserving the original wording, speaker cues, and any pertinent pauses or emphasis.
• Proofread your own work so the final text is clean and free of spelling or grammatical errors.
• Deliver each completed lecture as a PDF document using a consistent, reader-friendly layout (standard margins, 12-point font, and logical paragraph breaks).

If you have experience with Hindi typing tools, foot-pedal software, or time-stamping, feel free to mention it; these extras are welcome as long as the core transcript remains flawless. I will supply the first test lecture immediately and, once I’m confident in the accuracy, send additional files in small batches.
