Hello,
Your project requires a person with skills, not only in data entry but in spreadsheets. I believe I am the best suited person for this project. I will work with you and give you quality paper within the duration outlined. I work with an engineering firm, where I deal mostly with data entry and analysis. I guarantee you that I will give quality work, failure to which you should not pay me.
Looking forward to working with you, not only in this project, but in future projects.
Kind Regards
Rebecca
