Good Afternoon sir
Based on what I have read in your proposal, you are interested in having someone develop a simple command line application for you (using node.js) that allow you to manipulate c# files.
I would love to find out more about your requirements, but based on what I have been able to infer, a file manipulation tool that can create and update a file should take ~3-5 days to complete depending on how extensive you need to tool to be.
Payment will be accepted once the tool has been developed to your specifications.
Enjoy the rest of your day!
