Dear Sir!
I am applying to your project because I believe that I have the necessary skills and experiences to complete it quickly and well. I have a high level knowledge of and a lot of experience in Microsoft Excel (both 2003 and 2007), therefore I suppose, it will not pose a problem to me to find and eliminate all duplicated data in your file.
I have an outstanding attention to details, which is needed in order to complete your project, and I always check my work before I give it out of my hands. I also have a lot of patience and I am a hard working person, I never give up, until my task is finished because for me a big task like this one means a challenge which I accept.
For all these reasons, I would be most grateful, if you selected me to do this project for you, I will not let you regret it.
May you have any questions, please do not hesitate to contact me.
I am looking forward to hearing from you.
Yours sincerely:
Oláh Zsófia
