To whom it may concern:
I am responding to your advertisement for the post of ''Data Entry''.
I consider that my experience and interests match with your requirement and want to apply for the same position.
I also have experience of providing web research, data mining and data entry using MS Excel as my last projects.
I can start immediately and i'm comfortable with typing a high volume of information into a database.
Thank You and Hope to hear from you soon.
Sincerely yours,
Dacian
