Hello there,
This is Nila Sarkar, I'm a native English proofreader. I'll proofread and edit your 54,400 words document, so it can be perfect. I can make the document look natural by correcting any mistakes, or inconsistencies, and finding the flaws in the writing. I have spent 10 years experiencing the proofreading field of work. After finishing the document I will send you two files "One file will be a track change, and by this, you will easily see how much I've worked on your document, and where I changed things." One file will be clean, and proofread. You will be able to use the clean properly translated copy to do whatever you need it for. Also, let me know if you have any special requirements, or requests, I'll follow them too.
You can see an example of one of those projects in my portfolio here:

If you award me the project, I’d be pleased to discuss this further, and get started for you as soon as possible.
Regards
Nila
