Even if you wrote the book in your free time, this is my day job. The per-project cost many new authors would consider “manageable” would, if broken into an hourly rate, end up paying editors less than minimum wage. They don’t intend to pay what someone could earn making french fries; they just greatly underestimate how much time must be invested in editing.
Awesome book designers with a superb professional conduct. I've worked in marketing and advertising for over 20 years. I'm used to working with awarded creatives. When it came to designing my book cover, I wanted to make sure I worked with someone that had a knack for editorial design. Designing a book cover and the interior of a book might feel easy but, believe me, it's an art in itself. Since I started sharing my book cover, the only reaction I got where those full of awe. The quality of design and service was amazing. If you don't hire these guys you are either not publishing a book or you live on another planet.
Obviously there is a big difference. I actually started with screenplays (with some mild success) partly due to hearing that as long as you have a good story, the grammatical errors won’t be a big deal. Well, that was not true. Maybe if a producer liked the story or I was already established but every contest I entered always came back with feedback about the grammatical errors. Even if I won or placed as a finalist, I always received critique on that. Very little is spelling error, it was more about structure, etc.
