Dear Sir/Madam,
My name is Qiyu, Glenn, and I am excited to help in your project. I am highly proficient and experienced in the use of Microsoft Excel and Google Sheet, having to use them regularly at work and in school, and so I am confident that I will be able to complete your task efficiently and promptly.
I understand that I do not have a track record on freelancer.com as this is my first few times bidding for a project. Hence I am more than willing to take on your work for less than your budget for the opportunity to boost my experience on freelancer.com.
Do contact me ASAP and take this forward. I look forward to hearing from you.
Thank you!
Qiyu, Glenn
