Dear employer,
Your job interests me and i think i am the ideal candidate for you. That is primarily because your job is so tailor-made for me. I do not write for the heck of it, or for earning pocket money. I set high standards for myself in writing because this is all i do. I believe in completing my task well before deadlines and I promise you my work will be par excellence, with flawless English. You can ask me to write a sample if that is a prerequisite. Hoping for a response from your side.
thanks
Sunil
