I design webpages. I design graphics. I design Flash animations and interfaces. And I know how to make all of these look really, really good. More importantly, though, I pride myself on listening to my clients. I won't add or change a thing unless it meets with your glowing approval.
I also test every site I design in Firefox, IE and Chrome. To the visitor who only uses Browser X, it doesn't matter how lovely your site is in every other browser. They only see what's in front of them. Making sure everyone sees what they should is a job that I take seriously. However, I do charge extra for 100% compatibility with Internet Explorer 6.
