Dear Sir / Madam,
I am writing to apply for the job. I have read and understood the task. I can start immediately.
As an administrative assistant I had many similar jobs, I have got a lot of experience in these kind of jobs. I have an elance profile too.
I am reliable, accurate and fast. I always check my work twice before I send it to my employer. I hope my application will be taken into consideration.
If you want to measure my abilities, please send me a sample task.
Regards,
Emese
