I?d like to have lessons at the office (McCann Paris) twice a week, ideally 9-10:30 in the mornings. I can devote 3-5 hours per week during professional hours to my French studies and another 5 hours of personal time.

I am willing to do extra work for the course, online, at home and on the weekends. (I have Internet access at home and at the office.)
I will be in the USA for three weeks in August, but hope that I can begin my French studies immediately.
