If your already good at design I would go the flash route. Get flash, and do the tutorial, the tutorial should take about a half hour, plus it's interactive. Great program, and you can also export it as a html document, mess with it in dreamweaver or whatever. If you have Photoshop, you can even design pages there and export them as html, slice em up so they load fast, etc etc. Visit Flashthief.com they have tutorials, swf files for you to explore, and most of the top of the line artist using the software has a link on this site, so you can see alot great sites done in flash.
