Hi again!
Well, you know how I work so I guess I don't have to say it all again.
Just so you know how I set my prices : my rates are usually $0.04 to $0.05 per source word depending on the difficulty, and when the number of source word is unknown, my (rough) estimation is about 550 words per page.
4000 source words * 0.04 = 160, + freelancer fees brings this grand total. Hope the price look reasonable to you.
