Hi Daryl,
Unfortunately you can’t have that. And for a free theme that respects the rules on WordPress.org that’s pretty much impossible. If you could have 2 presentation pages, theoretically you should be able to have as many as you want and that’s not possible without custom post types, which are forbidden for themes on WordPress.org.
So your choices now are:
1. Look for a slider plugin and maybe a columns plugin (or something similar) and use them to create different content on two different pages.
2. Look for a premium theme that has that capability (premium themes usually incorporate this)
3. Wait for us to make a premium theme that will definitely incorporate what you need. (this option may take a while)
Good luck!
