Answered 8m a day?

Once you get the hang of it, and begin to memorize all the clues, there are ways of making exceptional profits per hour (upwards of 500k) using level 1 clues. However, this takes quite a bit of luck, and 8m worth of clues is a lot of playtime per day. So in short, possible, but not likely. Maybe alongside merchanting or something.

Note: I say exceptional in terms of low leveled players that can't boss hunt and such, as 500k isn't exceptional to most high-levelers.
