Dear project owner,
I am writing to you hoping that you will grant me the opportunity to prove my worth.
I've been doing these (data entry) kind of jobs for over two years now, however this would be my first assignment on Freelancer.
I am very accurate and fast, using high-end IT tools, and my employer has been very pleased with my performance. However, since I'm a student, I need extra cash for my faculty obligations so I thought this task of yours would be a good start.
Hoping for a positive reply at your earliest convenience, and I promise you will be very pleased with my skills and results.
Kind regards,
Sonja
