"Dear Hiring Manager,"
I'm interested in the position of Data Entry operator you recently posted. I have been a professional data entry operator for 5 years, and am very familiar with Word Press and Type pad. I managed a team of writers and data entry operator that produced a lot of data entry per week. I studied both in college, where I majored in English. I began my career as an assistant data entry operator at the local paper. Moving forward, I can dedicate 25-30 hours/week to your company, and my daily hours are negotiable. I'm very excited to assist you in making your data entry successful. If you give me a chance I'll prove my ability and experience as well - please don't be hesitate to contact with me directly to discuss this position further.
Best regard
