急！英文resignation letter

Mr. (xxx)
Human Resources Manager,
(---Org)
(----)
Date

Dear Mr. (xxx),

A letter of resignation
I am writing to tell you that I am leaving my job (in ---Org) on 30th Nov. as clerk after eight years.
Recently I am interested in another big company in a similiar (senior) post as it would enable me to gain experience of working in a much larger company with the opportunities for professional training and overseas development that the high salary to me brings to which I would tender my resignation now.
Thanks for the care and training I accepted in a most difficult situation and that I am grateful.
I hope that my request will be granted.
I resign out of my own accord.

I look forward to hearing from you.
Yours faithfully
Chris Wang.

你應該在文中提及：
1 你會去一間 better-paid 的公司工作
2 你可在文章結尾用一些帶有抱歉成分的字眼

P.S. 不要叫人作啊，這可能會違反「知識+ 內容移除標準」的啊！

Hope I can help you ^_^

加油！
