I am a french professional,
you are lucky and never worked that low :)
My deal : Reference me, give me a deadline that is workable.
for 300 to 500 words : Not more than 4 per day (unless you are ready for a bad work)
More than 500 words : not more than 2-3 per day.
After 1000 words, it's one per 2, but I doubt you want that much.
