Hi. You've found your best candidate for data entry right here!
I am a very detail-oriented person, so you do not have to worry about me missing out any characters in the project. I will make sure the details you wanted (address, date, value, etc.) will be inserted precisely. If you feel unsure of hiring me, I don't mind to take any test to prove that I am the best person for this project. I am more than delighted to take this job.
I would also like to ask:
1. What type of data entry project do you have (medical, business, education, etc.)?
2. When is the deadline for this project?
I look forward to your respond. I am down for an interview as soon as you like. Thank you for your attention.
