Wow dude! Your site looks great!
I'd definitely try to do some guest posts on some graphics blogs, maybe make a tutorial or two for beginners and post them around the web (on relevant sites).
A lot of people search youtube for "how to make a logo" and stuff like that so you could make a quick tutorial and then at the end say "hey you could save a bunch of your time and money and just have me custom design your logo for you..." etc. Get my point?
Press releases are another way to get the word out. That's a whole post in of itself so I wont do into too much detail there. Just google how to do a press release. It may cost a few bucks, but the visibility you'll gain is worth it.
And submit your site to KillerStartups.com.
OK, so I think I've given some good tips... don't just sit on them, take action! No mater what you do you have to do something in order to increase your business.
If you need anything else, please don't hesitate to ask.

P.S. - I couldn't help but notice the email "checked every 10 mins" at the top. It just doesn't come across as professional to me.
Not to say that isn't good, but it comes off a little needy towards your client and makes it sound like you aren't that busy since you have the time to read your email every 10 minutes. Not to mention it totally ruins your productivity with you being distracted all the time. Most successful business coaches suggest checking no more than twice a day. Personally, I'd just change that to a "we'll respond within 24 hours" or something like that. That's just my suggestion.
