Editing and design

My project involves editing and implementing certain design elements to existing materials. I need a professional who can help with grammar and spelling errors, as well as style, tone, and layout. Additionally, I have a specific style in mind, so I would need the freelancer to adhere to those standards while editing my materials. Although I am open to discussing some additional design elements, at this time, I am mainly focused on the basic editing. I am looking for someone who is knowledgeable and experienced in this area to complete the project in a timely manner.
