A museum near your home is looking for people to par-time unpaid job. Write a letter

Dear Dir or Madam, I am writing this email with regard to the available opportunities to work at the museum. I would like to volunteer myself to the job of marketing assistant. Since last year, when I moved from overseas, I have more free time than I would like to; for this reason, I have been looking for an unpaid work to do part-time. The opportunity at the museum is amazing for the reason that I love arts and also live close to the museum. To talk about myself, I finisehd my studies last year at the University of Adelaide's Marketing School. In addition, I worked at the marketing department of a famous library in Australia for six months. For these reasons, I believe I will be a great asset to you. Currently I am working every morning in a company in downtown; so, I will be free at the afternoons if you want me to work at the museum. Howerver, two times per month I have therapy at 3 pm, but if I get the job I can try to reschedule it. I am looking forward to hearing from you. Sincerelly, Herta Alexandre
