I expect to pick up a few errors - sometimes glaring, sometimes not so obvious.
Your site breaks the mould. I can't find anything wrong with it at all, it does what a commercial site should do - it provides exactly the information I would want if I was looking for your particular service, and does so in an esily read and understood fashion.
Well done, you've got it right. If I was really pushed to be nitpicking I would suggest that the image quality could be improved, and perhaps the homepage could be enhanced with a couple of larger images. The 'about us' navigation link should also be retitled 'Home'.
