Reliable proofreader


Can someone recommend a reliable proofreader/ proofreading services
I found plenty of options online but not really sure about their credibility and I need to
Send my whole thesis as a main issue I have is inconsistency in my use of tenses
Also, I have been using the American spelling and just discovered that I have to switch to the
British style because I am obviously studying in a British university. My supervisor has never commented
about my American spelling nor the inconsistency in my tenses because he has never read my work :)
My deadline is within a month, do you think I would be able to find someone whose willing to proofread 85000 words in two weeks.
Any recommendations for reliable proofreaders as I don’t want to risk it and send my whole thesis to just anyone
