Dear Sir or Madam,

I am writing to enquire about the tour guide training courses advertised by SGV Vocational School. I am very interested in becoming a tour guide because I enjoy travelling and learning about different cultures.

First, I would like to know more about the course content and its duration. How long does the training last and what subjects will be taught? In addition, I wonder if the apprenticeship is compulsory and where students usually have their practical training.

Moreover, I would appreciate it if you could provide more details about the course fees and payment methods. Although the advertisement mentions that no qualifications are needed, I would like to know if there are any specific requirements in terms of language skills or experience.

I look forward to receiving your reply soon.

Yours faithfully,
Minh
