Dear Maam/Sir:
I am applying today for the position of data entry worker, which I saw listed on Odesk.com. I'm available part-time and I can also work at home.
I know that experienced and talented data entry workers are an important component of a successful business. Their ability to enter data into a computer, key in text, and perform other clerical tasks is essential to the job. I'd be happy to join your team and add my skill to the pool.
If you'd like to discuss this job further, please call my home office at 09332143628 to set up a meeting at a time that works for you. Thank you for considering my cover letter.
Sincerely,
Christine Mae Canama
