Formal Inquiry Letter Dear Sir or Madam, I am writing to enquire about the tour guide training courses at SGV Vocational School, which I saw advertised recently. As someone who is over 18 and deeply passionate about exploring different cultures, I am very interested in joining your program. First, I would like to know the specific duration of the course. While the advertisement mentions that courses are held year-round, I would appreciate it if you could tell me the start dates for the next intake and how many months the training typically lasts. In addition, I wonder if you could provide more details regarding the "low cost" mentioned. It would be great if you could send me a full breakdown of the tuition fees and any additional expenses for materials. Furthermore, I am curious about the apprenticeship provided; I would like to know which companies you partner with for this practical experience. I look forward to receiving your reply and hope to start my training soon. Yours faithfully,
