Power BI mentoring

I am fairly new but enthusiastic about Power BI. I am building a query based on our company data and I have some challenges that I think a good Power BI consultant can help me with in a short space of time. If this small assignment works out then there are bigger collaborations on the horizon. The questions to be solved are about relationships between tables, setting up an if statement using SWITCH the function and creating a box and whiskers plot. I can share the data tables and view the PC activity using Team Viewer.
