    A Copywriter with Imagination

    United Kingdom - Last active: 19 hours ago - Tests: 5 - Portfolio: 10

    You should work with a writer that knows how to send a different message. You don't have to settle for the same bland content as the rest of the web.

I have a BSc in Marketing from the University of Ulster and an MSc in International Marketing from the University of Strathclyde. I have written hundreds of thousands of words of content in prior roles as a business analyst and a copywriter. Now I have my own copywriting agency, and that is called Prime Scripting Ltd.
