editing an e-book

I'm looking for a talented freelancer to help me edit a comprehensive e-book with a word count of more than 50,000 words. The deadline for this project is within 1 month. This project has no specific editing style though APA, MLA, or Chicago can be used. The ideal freelancer for this job should be able to edit the document in an accurate and reliable manner, while adhering to the stringent timeline. The book will need both proofreading as well as formatting.
