In my experience, it seems the type of work you're requesting would function best as a Flash site, and those can be very pricy ($500-1000+ for a Flash developer alone, judging from professional Flash forums). I can't speak for the whole community, as I am a new member like you, but I'm not sure that it's in your best interest to ask for web design here. You're probably better off asking us to produce maps, and searching professional Flash or web developmentforums (like flashkit of designphorum, if those sites are still active). But, yeah - while you might be able to find a good number of useful and helpful fantasy cartographers here, websites are pricy endeavours and something else unto themselves. I'm sure we could help with creating the individual elements, though. If you put up specifics for what you want, I'm sure people would get around to them quickly.
Good luck! (And someone correct me if I've said something wrong.)
