Author AK Weller, well know for her thriller books and short stories, is an amazing graphic artist. She designed the cover and illustrations for In Letting Go, my book of poetry, and handled all the formatting and internal design.
She has a monthly newsletter, which you can sign up for here. In the latest issue, she introduced me as a writer and poet, and featured my new book! She has been very generous and is amazing to work with! If you need a great graphic artist, I recommend you check out her company, Westley Enterprises.
And for editing, I hightly recommend Lisa McCoy. She's another amazing person, a champion of self-published writers, and she's the one who turned me on to Westley Enterprises!
