Hi Sir/Ma'am,
I see you have advertised for an English Speaker and I'm very interested to work with you on this project.
Please tell me specifically what the project is about as this was not described in your offer. I will be available to complete the task in 10 days for a budget of $250 dollars.
I am presently setting up portfolios, however, as a native English speaker, and as a supervisor in my regular 9-5 job, I have had to prepare numerous reports, write minutes and do transcriptions, all done in excellent English. I have also done transcription work on fiverr.com. These transcriptions had to be done with no grammatical errors.
I am sure we can both agree on an amicable delivery time when we discuss this project.
Please consider me as my aim is to please my awesome clients.
