Hello! I am a native English speaker, and I have recently completed my Master's in English language and literature. I have two years of experience teaching academic writing at the university level, and three years of experience working as a freelance proofreader.
As you can see from my completed work, I have a lot of experience proofreading technical documents. I would be able to proof your report within 10-12 hours, and I have no problem signing an NDA for you. If you would like, I could also keep "track changes" on as I work so that you could review my work.
If you have any questions, or if you would like to see a sample of my work, please do not hesitate to ask. I look forward to hearing from you soon =)
