E-mail cover letter

Dear Mr. Arnold, I have come across your want of a mechanical engineer through your website and would like to be one of the applicants to the respectful job. I am a qualified mechanical engineer from the Harvard University 99-03 batch. I have a previous work experience of 7years. I am expecting a salary of a minimum $ 45k monthly, as you know this is a far more challenging job than the one I a6m executing now. I assure you that I would be worthy enough for such a good pay and for you to barrage my capabilities I am including my resume with this letter. Thanking you, John
