Dear Sir or Madam,

I am writing to apply for a volunteer position at your Heart to Heart Charitable Organisation. I would like to contribute my time and effort to support your meaningful activities, especially helping people in need.

I am interested in working at your head office, where I can help welcome guests and visitors, as well as receive and sort donations. I am a reliable and hard-working person, and I enjoy working with others.

I am available for an interview any afternoon during the week or at weekends.
If my application is successful, I can start working immediately or at any time convenient for you.

Yours faithfully,
Nguyễn Hoàng Gia Bảo
