本科生英文求职信

dear sir,
　　i would like to ask you to consider my qualification for the position in sales that you advertised in jobspower.com.
　　i graduated from the college of business administration in june of 2013. since that time i have been taking night courses at city polytechnics in sales techniques and advertising.
　　for the past four years, i have worked as a shipping salesman for maersk, one of the world largest shipping company. at present i am their chief salesman and account for over one quarter of the sales in asia. before my present employment, i worked for abc chains boutique as a salesclerk. we worked mainly on commission and i was able to earn a substantial amount although i was very young.
　　i would like to make a change now because i feel that i can go no further in my present job, i feel that my ability and my training should enable me to advance into a better and more responsible position, and it appears that this will not be forth-coming at my present position.
　　if you would like to know more about my ability, i can be available for an interview at any time convenient to you.
　　sincerely yours
