sir/madam
having gone through your project, I am qualified for this job. I have spent time working on some projects of similar nature, and really learnt a lot. I also have a paid copy scape account to check for plagiarism before sending work to you so you won't have any issues with my work. also, my English is excellent and my work would be error free and interesting.
I am also able to work with your budget and I would deliver your articles right on time. I would love to be given a chance to do this job, and I don't mind writing an article for you as a test. I would also love you to drop a good review for me so I would put in my best. looking forward to be awarded the job, thank you very much
