agreed on the notepaper. unnecessary and doesn't really work with the rest of the design.
as you mention you've been doing GD for 20 years or so, I would draw on your exp. with page layout and consider that in relation to your site. for instance it is quite frustrating to have to scroll down to see your content, even just a few paragraphs, because your background image (the lights) is taking up so much space, and your margin to the top is substantial.
in the end a website is just another advertisement, so the same rules there apply here. you simply cannot expect people to scroll for your important content, it must be visible in the viewport straight up.
if you have experience in advertising / marketing then you'll be able to pursue more traditional methods along with your word of mouth and be reasonably successful in your local area, but you simply must learn at least the basics of SEO, and semantic markup, to ever expand beyond that.
unfortunately its not as simple as just having good hosting, although leaving the bad ones alone certainly wont harm your efforts. you need reliability over price, always - you ALWAYS get what you pay for.
I found this in your code
<!-- Save for Web Slices (homepage.psd) -->
tsk tsk!
exporting all slices from photoshop is a bad habit to get into. It makes you become lazy at coding, more reliant on imagery and less on css, and isn't very flexible to future changes. learn as much css for design as you can and leave that button alone!
overall not a bad start, remember the majority of internet users are NOT on an iMAC so its best not to design something that looks great only on that!
remember IE sucks always, so it needs to be checked. as does FF, Safari, Opera, Chrome and Konqueror at the very least. and at multiple resolutions 1024x768, 1440x900, etc etc.
go with your design gut for the page layout...thats all i've got to say.
