Also, playing hotdog-not-hotdog on a receipt, looking for the price of eggs, and then entering them, is a very different job than the open-ended case of "enter all the relevant information from this receipt. There is large classification task that also has to take place to group name-brand items into generic categories (an open set that you don't know from the start) suitable for analyzing.
So, I've actually done similar work to this: getting paid piece-rate to manual enter data from paper invoices into an accounting system. It was so long ago I can't remember how fast I got at it, but it was way slower than 2 a minute/120 an hour. I doubt I got much more than a dozen an hour done. So, my gut reaction is that your estimate on the human cost is off by an order of magnitude.
