My skills are in my time-management and efficiency. I have written Conversational Copy and Blogs of 1,200 words or less, and I have written books 60-100,000 words, but nothing comparable to your 7,000 that I could show for a sample.
I'd be happy to send you my Blogs and books, however.
I specialize in high-value content, all of my work is 100% original, inspired from in-depth research.
I look forward to the chance to talk more!
