the fee

I was wondering how much it is more or less the fee for a translator per day. I heard from a friend it could be around US$ 100 per day, another friend mentioned a number much way lower than that.

And now I'm in doubt, should I mention around 100 or less than that? I'm afraid the person would say it's too expensive. I know that bargaining can be done to bridge the two of us, but I don't like bargaining :D

So....???
