formula and chart to measure cleaner's performance

I'm looking for a freelancer to help me create a formula and chart to measure the performance of my cleaner. The primary metric I'll be using to measure the performance is quality of work. Fortunately, we already have a data collection system in place, but I'm looking for assistance in presenting the results in a more detailed way. Specifically, I'm hoping to receive a detailed report with charts and graphs that will give us a better analysis of our cleaner's performance. If you think you have what it takes, please reach out and we can discuss the project further.
