Hi,
You may not select the right candidate without knowing what your project on writing codes for your Excel file to automatically create backup in a SharePoint site will look like. Fortunately, I can complete a part of your job before you award the project.
Before you award this project, I can complete a part of this project as a proof of concept. This is so that you can be confident of the hands you will entrust this task. If you are satisfied with the result, you can go ahead and award the project.
I’d love to discuss more on what would make this project a success for you. Can we have a quick chat?
Thanks for your time.
