Paris has good value for the money and its possible to go there relatively inexpensively but nothing in your question suggests that you'll settle for rock bottom costs.
So figure at least 120 euros/night for your hotel and 100-150 euros/day for all your other costs exclusive of shopping trips. So you're looking at 220-270 euros/day ($307-$378/day).
You can do it a lot cheaper of course (or also a lot more expensive).
