Polishing of a Ghostwriter

"Hi, I have an ebook with 104 pages and 26,843 words in Times New Roman font, size 12. I need the text improved to a more informal style to make it easier to read. I also need the text to be adapted to British culture. You will have the freedom to change words, modify an entire paragraph while maintaining the main idea so that the text is even more comprehensible. I need you to polish all the content even more aggressively, trying to keep the main idea of the ebook, which would be this: ‘The ultra-restrictive secret that personal trainers use to burn 8 kilos of body fat blowtorch-style using only a ketogenic diet in 30 days !!!’ All this text so far is just a ‘Monster’ file created with bits and pieces of various different contents on the subject. As a ghostwriter, your aim would be to give meaning and life to the text. Honing it as you see fit until the content is able to fully deliver the promise of the cover. If necessary, other ideas, steps, tactics, processes, stories can be inserted into the text. Also, if necessary, you can and should delete sentences, paragraphs or anything else you feel is unnecessary in the text. We should aim to be objective, very objective, removing trivial information, keeping or adding what meets the promise of the cover. Prioritising the reader's time as much as possible with the urgency of reaching the final goal. The deadline for completing the project will depend on your availability, obviously trying to finish as soon as possible. Please be aware that if the work turns out as expected, I will certainly have more content to send you. I'm looking forward to seeing what you can do with this project. I look forward to receiving your proposal."
