I am a writer with a first class degree in English, Creative Writing and History and over ten years professional experience. I currently write academic literature for a couple of online essay assistance sites and content for a small yet diverse portfolio of clients.
I shall infer that the primary concern for you - with the axiomatic exception of the possession of the talent and ability to actually fulfil the requirements of the role - is that the person you eventually hire is professional, consistent and reliable.
We'll get to my considerable literary talents in a moment. For now, allow me to assure you that I will deliver all mutually agreed upon, flawlessly written and meticulously proofread materials on time and to your complete satisfaction. I have a verifiable record of hitting deadlines and surpassing even the most scrupulous expectations.
My extensive experience is matched only by my prodigious talent. I am certain I am the best candidate for this job. I have the talent, the relevant experience, the appropriate skill set, and an unrivalled desire to succeed.
Good luck and I hope to hear from you soon.
