I am a structural engineer by trade so I'm familiar with technical jargon and report-writing formats.
While I do the necessary proofreading, I can check that the ideas flow in a coherent manner. If you like, as I go along, I can provide suggestions on how to paraphrase some sentences where possible.
All I ask for this nominal fee is that you provide me a positive review or a 5-star rating once the job is completed.
I hope to hear from you soon.
