Dear Sir or Madam,

I see your advertisement in a student magazine and I’m interesting to know more about your diving courses. First of all, I should explain that although I can swim I’m not very confident in the water. But you mentioned your advertisement that your instructors are full qualified. Thus I believe they’ll be able to teach someone as me to dive. I have one week’s holiday in the three week of June and would like to know that if there’s a course running at that time. How much does a week’s course worth? Finally, if I decide to go ahead, are there any special equipment I need to buy or is everything provided by your company?

I am looking forward to hear from you.

Sincerely yours,

Tom
