Can you help me with job application

Its my first time so I think there will be a lot of mistakes, I appreciate your big help so thank you in advance!) I need to submit it for part time job. I think it shoudnt be very formal. I live in Denmark so people like informal style of communication very much. ere is requirements for job if it will help to help me)): I must be stable, honest, not afraid to take hold, a sense of cleansing, as well as understanding of the importance of that Cafe must be always clean and tidy.

Dear Sir,

I saw your advertisement on the internet, so I’m writing you about job of cleaning assistant.

My name is Viktoria. I’m a student of UCN who came from Estonia and now I`m searching for a job. I don’t have any desire to live for my parent’s money, on the contrary, I really want to support them, therefore this job will be very important for me and I will try as hard as possibly.

I don’t have experience with cleaning, but I was brought up by my parents who love cleanliness, especially my mother. She is obsessed with it. She gave me very clear understanding of its importance. Also I appreciate criticism; I believe that it improves my skills as well as my personality. By the way I’m quite shy person among strangers; however I’m communicative person with people I know, so I hope it won’t be very big problem. In addition Work time suits me; I think it’s better to work at the weekends than mix work with studying. Moreover I will be ready to work extra time if it is necessary.

If it’s needed I can work for unpaid trial period so this way you has nothing to lose and can see if I’m suitable for work or not.

Thank you for your time.

Viktoria
