Design ideas for choose yes/no path type course

Hi all,

I am trying to mock something up to show potential client about a course. Currently I have a very rough draft of their PPT. It stars with a statement and then underneath there is a YES or NO choice, depending on which they click they will be taken to the respective slides.

It is also presented by this host(the idea is she will walk you through the slides) they have used clipart and I want something more modern but don't have graphic design background that I can sketch something up, should I stick with illustration or real person image for the host.

I was thinking of a simple branching type course but if there are other ways, I would like to wow them and get their buy in.
