Welcome to the Industry, and very nice site and icons.

But, I have some critiques...

1. When I am in "Why Swivel?", then I switch to "Support" the link disappears, maybe you should remake a new image, and replace the "Why Swivel?" when "Support" is clicked?
2. "Support" is in Why Swivel and Company?
3. When I clicked "Company" I saw the company details, and then clicked Contact, then the contact form popped up. Then once I clicked the "Company" link in the header to reload the page, the contact form remains, until I click the "Company" image.
4. Order buttons should be click able.*It can and will decrease sales.
5. Plan Comparison page is a must. *It can and will decrease sales, seeing as most consumers would like to see what the plans have in common, and what is missing.
6. The site looks rushed? For instance, the content isn't heavy? There is no Terms Page, Legal Page, the current pages look plain.

Not trying, to be me rough or anything.

I agree with Chaos King, the illustration is amazing, and I like how all the icons are custom and not the overused famfam ones (nixism's lol). On top of that, I also like your use of javascript, I believe?
