virtual studio background like a news virtual background for Camtasia.

I need a virtual studio background like an interview virtual studio background for Camtasia so I can use it for green screen. If the virtual background is a premade template you must be able to change the colors and text and add the company name. The template must not have wood colors. You must be an expert at making and editing virtual backgrounds. I will need to see samples of the templates. You must show me how to do a live presentation using TechSmith Camtasia, and show videos on the background screen while the interview is happening. And how to see the screen during the recording so I can control what the viewer sees during the presentation. See attached file.
