Hi,
I am interested in your project and I would love to work with you. I noted from the project description that you require someone who will be involved in some sort of data processing that will require Excel. I have worked in similar project before; I have extensive experience in data entry using MS excel, databases etc.
I am available to work on this project. I am hardworking, diligent and pay attention to details. I assure you that I will exceed your expectation if given the opportunity to work with you on this project, within your budget and in record time.
Should you have any concern as regards my proposal, do not hesitate to contact me.
Looking forward to hearing from you.
Thank you.
