FYI, to go totally by the rules I believe unless you have permission your not supposed to use ISA's logo (the banner at the bottom) without there permission. You may have that already anyway. I was just yesterday looking into added their logo, and I couldn't justify it after reading their document on proper branding... and, I think you need to have your name under the CA logo as well as the number.
I've seen more people not follow all the rules to the dot then I've seen do so, just letting you know.
Otherwise, I think the site is beautiful. I wish mine had the quality presentation that yours does.
