I like it on the whole, you have manipulated Joomla pretty well!
Only things I'd think about changing:
- The way the links are at the bottom, looks like they have been added in a hurry?
- The header image at the top of every page - I have a pet hate against them although it does make the page look more alive.
- Heading font - perhaps a little too casual and doesn't work well with some of the buttons (like Get A Quote)
