Proofreading and editing of ai content .

I have a research paper that requires proofreading, editing for mistakes, and removal of generated AI content.
I need help with the following:

Proofread paper for grammar, spelling, punctuation errors
Smooth out awkward phrases and improve tone
Check conformity to Harvard style guide on citations
Validate logic flow and soundness of arguments
Identify areas that seem artificially written
Completely remove any automatically generated paragraphs while maintaining cohesion
Rewrite removed segments with original writing in my voice
Expand thin areas that need further support
Perform final polish for clarity and consistency

The editor should have experience with writing standards. Most importantly, you must be skilled at detecting AI/non-human generated content and able re-author those sections meeting originality requirements.
