A hunter would require voice acting and a lot more effort. However, a note from a hunter would be very easy, maybe a bit of food left for you, while you recover.
It would be 100kxPercent+Basix40, until we have those numbers we can't give a final answer. If we say Percent = 5, Base = 30, it comes out as 6200 gold. But that's just numbers pulled out of thin air.
(I think I've seen a couple of games which take 7% per death, but they don't take items. Just for reference.)
Oh, and by my standard, that's a wealthy character. If it was level 5 with 500 gold, it'd be 175, which is a much larger proportion.
