Hi Laura,
I'm actually studying in Paris right now. I'm doing my MBA at Schiller International University. Since you speak French, it would be so much cheaper for you to study at a French University, about 500 Euros tuition for one year I believe. Here is a website you can refer to:

If you are serious about this, you should be an appointment with the French embassy in your city to find out more.
Bonne chance!
