Hi,
I offer you my copyediting service for your 3000-word article for USD70 (including 10% Freelancer fee), to be completed in 1 day. This service includes basic proofreading (grammar, punctuation, and spelling checks) and sentence restructuring.
Please note that I use MS Word Track Changes for my copyediting service. At completion, you will receive one .docx. file with track changes visible to you and another 'clean' ready-to-use file with all track changes already accepted.
I obtained my PhD in chemical engineering (my research topic was on carbon capture and storage), so I'm familiar with the topic of gas recovery. My previous proofreading and editing work include PhD proposal, ebooks, and web contents. A sample of these can be provided upon request, but you will have to initiate chat because I am unable to attach files at bidding stage.
I look forward to working with you.
Best regards,
Ili
