Hi..I would love to take up this job offer as it concerns my skills and most importantly my interest.
I have good amount of knowledge and experience in Excel/ Spreadsheet operations and I believe that, if given a chance, this job opportunity would both be beneficial to you as an employer and me as your helper in this task.
If awarded this project, I can assure you of quality work and timely delivery at reasonable cost with my previous experience. Also this project would help me gain experience, knowledge and also upgrade my skills.
Awaiting your positive reply. Thank you.
