Hello,
Having read your project description, I believe that I am perfectly suited to this task. I have been freelancing as a proofreader for over 20 years and have worked on a wide variety of academic papers such as dissertations, theses and research journals, to name just a few.
I can provide you with a professional result for your 300 word abstract, ensuring that the correct wording, grammar and spelling is used, and also make sure that all punctuation is right.
I can complete the project in 1 day and hope to hear from you so we can discuss matters further.
Best regards,
Stephanie
