Dear Sire/Madam,
I am excited for this opportunity.
I have long worked using spreadsheets programs in my line of work as an engineer. Thus, I am confident I can meet and complete your project within the proposed budget and time frame.
If possible, may I get the details of your project to better understand your expectation, please?
Thank you. I look forward to receiving your positive response.
Sincerely,
Ronald Maramis
