Leaping Lexicons, Eric.
That's a pearl of a miserly posting you've uncovered there. Personally, I wouldn't even read the job description a second time for less than $50.
Leaving your mathematics and the blood-sucking budget aside for the moment, a posting like this should raise some red flags.
If, for example, "separate files can be generated automatically fairly easily", then he should be doing it.
Any time I'm told how simple an assignment is, I know it's going to be a major headache.

And do I understand correctly that he wants the talent to research and define the words?
He should be doing that, too. And - with definitions - that would bring the word count way, way up, no?

Iif you're practicing job evaluations, this one yells, "RUN AWAY!"

But, were I forced at gunpoint, I'd calculate 8,000 words (without the definition), including research, reading, editing, and filing, at 60 seconds per.
That brings us to some 130 hours' work. At a rock-bottom $50/hour, we're talking about six thou.
(I'd also quake a lot.)

But when he says free-lance, he obviously means it.

Head-Shakingly Yours,
