Dear Sir/Madame,
I am very interested in translating your article for you. I am Swedish but have lived in the U.S. since 2015 and am fluent in both Swedish and English.
I have a certificate in General Proofreading: Theory and Practice and have a great eye for spotting typos, grammatical errors, and inconsistencies in tense and formatting.
I would be delighted to help you perfect your work, and you can always count on me to be punctual, professional, and above all passionate about making your work the best it can be. Thank you for taking the time to read my proposal.
Sincerely,
Erika Zheng
