I see your advertisement in a student magazine and I'm interesting in diving courses.First of all,I should explain on that although I can swim I'm not very confident when I in the water.But you mentioned your advertisement that your instructors are full qualified.Thus I believe they'll ba able to teaching someone like me to dive.I have one week's holiday in the three week of June and would like to know if there's a course run at that time.How much does a week's course cost?Finally,if I decide to go ahead,is there any special equipment I need to buy and is everything provided by your company? I am looking forward to hear from you.
