Pouvez vous me corriger S.V.P?

I am talking to you to apply for a job of an Island caretaker. I am 20 years old ans I am a part-time student. I'm so excited about this job because it's really the best job I haven't seen. What is better than spending 6 months on an Island and taking care of some amazing little things who live in the ocean. I have taken some swimming lecons while 10 years. It will be really good because I travelled the world but I never was in Australia. I am an responsible and hardworking person but I am so funloving. About my nationality, I am a persian girl but I lived all my life in France. Don't worry, I am good at english.
