Prices of Paris attractions?

I want to prepare a budget for visiting Paris, but most of the web sites don't have much price info.
I need info for the following:

Cathedral of Notre Dame
The Eiffel Tower (top)
Arc de Triomphe
Versailles
Louvre
Fragonard Perfume Museum
Basilica de Sacre Coeur






Answer :
Actually, all of the websites have the prices on them, and in English too. The only exceptions are the two churches.

Notre Dame - no fee, unless you want a guided tour, then it's 6 € - http://notre-dame-de-paris.monuments-nat…
