Hi Jamessamdownes,
I ended up making all new pages, setting one of them as the homepage and moving the two main landing pages into "Secondary navigation" for them to appear as menu items. Then I just created my pages and linked to those pages from the landing pages.
As mine is an online portfolio, I was advised don't worry about a "home" page as such, just show the user the thing you want them to see the most (in my case it's my UI/UX Casestudies), so that page essentially became my homepage.
Hope the image of my final IA helps.
Cheers, Jai
