Dear Sir / Madam ,
It gives me immense pleasure to send you this proposal to write a content for a website as specified by you and research on the topics as specified. Writing content has been my hobby for the past few years but now I have not thought of though to take it up for professional use . I think I am the best to do it as I bring in fresh ideas , fresh concept and fresh though process to this subject. I wish I can deliver as per your standard and keep up the relationship on a long term basis.
Thanks and regards
