Build Digital Marketing Dashboard Using Spreadsheets

Hello, I am in need of a talented freelancer to both design and build out a project for me that marries the standardized data of several spreadsheets each representing a separate campaign to create a Dashboard that allows my clients to look at all of the data across the sheets at once. We will need the ability to update with new spreadsheets monthly. I was thinking Google Sheet and Google Data Studio would be the best route to build the project but am open to hear other ideas. I have attached the campaigns of one of my clients as example data. If interested please let me know the estimated ETA for the project as well as your cost. Thanks in advance.
