I have vast experience as a freelance writer and I think I am a qualified candidate for this job. Over the years I have written hundreds of articles and this piece should be a piece of cake. I can also follow specific instructions you can give me.
If you hire me today, I can start working on this project right away. You will not be disappointed.
You can also assign to me a smaller task of a few paragraphs that I could write for you for free for you to test me. Please note that I will not write anything long for free, only something short so you can get an idea about my writing ability and style.
