I've been working on the site locally, but I've uploaded it here. The host won't let me log in and add links to the nav, but the finished site will have three links in the nav, the third one with .sub-menu drop down links. The drop downs seem to be messed up by the responsive code.
I managed to get the website nice looking on an ipod touch using a separate stylesheet for mobile devices. However the nav still doesn't move out of bar form when you resize the window on a regular computer, and I suspect it might be messed up like that on the ipad too.
My stylesheets are here: style.css mobile.css base.css screen.css
Responsive stylesheet: here
The stylesheets I was using before implementing responsive nav are stashed here: style.css mobile.css base.css screen.css
