"Respected Client,
I am Santa Maria from Parramatta, Australia. I hope you are doing well. I would like to offer you my assistance in translating the content for you. I have extensive experience from more than 7 years in translating and proofreading from Japanese to Vietnamese and vice versa. I have an excellent grasp of Japanese as well as Vietnamese.
If you have any doubt about my work quality please check my profile and previous work portfolio from here: https://www.freelancer.com/u/santa19
Could you tell me a bit more about the project that how many words do you have, when you need to have completed, in what format is the text that needs to be translated?
If you feel there is a mutual interest, I would welcome the opportunity to chat with you to learn more about the project and how my qualifications would be a good fit.
Best,
Santa Maria
