Hello,
I'm reaching out to express my highest interest on this position. I am a native Indonesian, and Bahasa Indonesia is my first language so I believe I suited this requirement. I can help you to translate the documents, and for time availability, since I don't have any work commitment at the moment, I can start anytime in case this is an urgent work.
If you need further details about my work history, please let me know. You can reach me through message, I'd be more than happy to assist you with the information that you needed. Thank you for taking the time to read this proposal, looking forward to hear your response, and hoping you can give me a chance to do business with you soon.
