Steve,
First off, congratulations on your shop launch. My name is Kellye Parish and I am a professional editor and writer. I'm bidding for the position of copywriter on your website.
I think that I would be a good fit for this project, as I am very informed on organic foods/fair trade/anti-GMO issues, and actually run an organic farm called Two Monks at my home in Alabama. I'm willing to send you a partial copy of our business proposal for a writing sample, since it would give you some idea of my knowledge in the field.
I just edited (and partially rewrote) an 180 page document over the weekend at my day job, if that gives you any indication of my speed in writing-related work. I'm fast, accurate, and I stay in touch. Please let me help you make your website a success. See PM for further details.
