Sir/Madam,
I've been working with MS Excel for more than 3 years, creating Macros to ease the job, and formulas to aid the process. I do my best to have my client satisfied with my work, I ask what the client need, what they want as the outcome and if there is a special instruction, after which, I deliver on or before the required TAT of submission.
I hope I'll be able to work with you.
Thank you!
