Cartoon portrait

Digg.com had a link to this guy who does cartoon portraits/icons he calls: Iconize Me!. I REALLY like the style and would like one for this site. However, it looks like he only does a few a year and closes the site down for new purchases for months at a time. As it looks like it's too popular for what he can handle*, I'm wondering if anyone else is offering something similar online? I do NOT want a carnival caricature. Those are all over. These are more like a comic book. That's actually where I'd expect this service to pop up. Are there some comic book artists who'll do portraits of people in their style? With all of the attempts to make money with online comics, I'm surprised I haven't seen this somewhere before. Maybe I'm just not searching for the right words.

*Basic economic theory he might want to think about: if demand outstrips supply, you raise your prices to manage demand. Especially if the price isalready ridiculously low. I read that the reason he can't do more of them is that his day job gets in the way. If you're so busy with people lined up to give you money for your hobby, you may just have a viable business on your hands and you can quit your day job.
