It's a nice layout.
I find the scrolling pictures a bit too fast too look at properly...try and slow the scroll speed down.
Try and add a favicon...I know it's a small thing, but for me makes a difference, especially with multiple tabs open, as I can recognise a site from its favicon.
The query form is good, it means you don't need to go into your email to contact you.
It's good that all your downloads are in pdf...well done
That's a common mistake, as not everyone has MS office or equivelant.
The FAQ is good, but the site map shows an under construction page...try and sort that ASAP-there's nothing worse than an under construction page.
The location map takes quite a long time to load. Maybe just use an image rather than an embedded map.
How did you set up the google webmail??
I'd give the site 8/10, if it weren't for the pages under construction, and the images scrolling a little to quickly...it would have been a 10.
Hope this helps
