Colors, man, colors. Noone wants to be navigating around a dull, gray site, especially if they're going to be trusting you with their site. I think you should definitely employ HTML 5, and some more CSS to give it a little more pop and make users know they've come to the right place.
Also, dude, $500 for a site? Whew, a little pricey. Just my opinion as a freelance web developer.
If I may, you might consider changing, "If you are interested in using my business then feel free to contact me......." to
"If you're interested in using my services, then feel free to contact me......." Changing from using "business" to "services" gives it a more professional sound and feel as you read it.
Question: Why do you have two contact locations? You have the "contact me here" as well as the email address dedicated to your web sight. I never place two emails on the same page, because it tends to confuse visitors, who because they aren't sure who to contact, end up not making any attempt at all. That said, I would consider using just your scynge address, since it leaves visitors with the feeling they are getting in touch with a real person and not some standard form.
Overall, you have a clean site, that loads quickly.
PS, With no disrespect to Mark255, if anyone is offended by how the gal on your main page looks, maybe you don't want them as a client. I also agree with yozo67, in that you should think about using css and HTML 5. You might also think about having an hourly fee, instead of a flat rate. After all, for a potential client, $30 an hour is much less intimidating than $500. When calculating your time, always deduct a portion to make up for "your" mistakes.
