Dear,
Being a professional writer with diverse writing experience on many subjects, I strongly feel that I would be able to provide you a befitting work. I do understand that there work should be both impressive and enticing, with a tinge of promoting our product.
Proofreading, editing and producing original works is my forte.
I value long-term relationship and thus quality is my passion. While I have to write literary English for some of my clients, you won't find me lacking in easily understandable and purely professional discourses.
Looking forward to working with you,
Zubair
