From some minor historical experience with Mechanical Turk, I bet you could get humans to do this for one or two cents per receipt. You do them all three times for error checking for $0.03-$0.06 per receipt. I used to pay a nickel for much, much more than 5x this amount of transcription per job, and I got the feeling that I was overpaying based on how eagerly I got responses in and that I saw a lot of the same workers repeatedly. These days, are MTurk workers simply feeding it into AI anyway, though? It's been a few years since I've run an MTurk campaign. At the time it was clear that humans were really doing it, as you get emails from the workers sometimes.
