The reason why I think I deserve to write these articles for you are as follows:-
1. I am hard working and punctual. You don't need to worry about the time when it comes to me writing for you.
2. I thrive for the best. If you don't like my articles then you can ask me and I'll edit or even write a new one for you. Your satisfaction is important to me.
3. I have an experience of about three years in writing articles.
That's all for now. Thanks a lot for your time. I look forward on working with you.
Have a nice day :-)
