Dear Employer,
I am interested in working on your project and will be able to start right away with the work. I have very good writing skills (I can always provide a sample if you need) and will provide you the articles in time while maintaining a high quality. I have been writing here and there for past two years and I can ensure a daily output of 5-6 500 word articles.
Looking forward to hear from you. I will be very grateful if you provide me an opportunity as I am still on the lookout for my first freelancer project.
Regards,
Sanjeev
