Well, I do a lot, but I think I can break it down to three areas; web design, web application development and hosting.
Web Design
I do every aspect of web design. From conceptual artwork to html coding, back end programming and hosting. And if that doesn't make to much sense to you, it just means I do everything from start to finish. I like doing sites for smaller businesses, the sites I make are all custom, not from a template, I put my name on the sites so I want them to be sharp and very functional. My sites are all dynamic, this means that you can update your website anytime without having to contact anyone to change one little thing.
Web Application Development
The name pretty much says it. I really enjoy developing small custom web applications. Anything from a full CMS type SAS application to a DVD catalog system. I code in asp.net using a Microsoft SQL backend, I keep up to date with all the latest and greatest, AJAX, LINQ, .NET 4.0 and SQL 2008 R2, it's exciting, after all I am a computer geek.
Hosting
It started off just wanting my own server to host my personal stuff, but then kind of expanded and now I lease servers from a dedicated datacenter. I offer windows based hosting. xI don't really charge too much, I just kind of get enought to cover my costs and make a little on top.
