Question / Help Need some help, preferably I would like to hire someone...

[smariaca]

I am trying to find a way to film a presentation in front of a 70-inch smart board with two video inputs, a camera on the presenter (in from of the smartboard) and a feed of the screen content with the ability to toggle between the two 'on the fly''. I would also like to use my iPhone Pro Max as the camera and also use a lavalier for audio. This video will be recorded and controlled by a Mac so it can be edited, etc. Appreciate any help -
