Correção de Texto ''A formal e-mail''

Dear Sir,
I am writing to ask for information about Tennis courses in different parts of France. I and my friend Lane interested in a beginners course with private teacher. We live in London and we started playing tennis 1 year ago. We want to improve our skills and get to know the country and meet new players.
We have looked at the advertisement but there is no information about course's price, when it starts and finishes, how many students are going to travel with us. Could you please send me this information? If possible call me, the number is 9476-0076, because I want to know abbout the discounted from students.
I'm looking forward to hear from you.
Yours faithfully
Alejandra.
