OBS Studio Expert

I need help installing some graphics into OBS Studio to use for online meetings and presentations, and how to set it up and use them during the meetings, and I need help installing them into Camtasia for use in videos. You will need to show me how all this is done. This should be an easy project for an OBS Studio and video editing expert. Do not just send me online how to videos, I prefer direct discussion. You must speak and understand English perfectly and be able to have online conference meetings. You will need to sign my NDA.
