What's in a name?  Serious or fun?
arvernus: I'd recommend to register both domains for a few bucks and ask again with naming the actual working titles.I think I personally would prefer the serious name.For your logo: we got ours from http://www.designcontest.net/ - you pay $150 (or as much more as you like to) plus I think about $20 fee and describe what you want. You get several logo concepts from several artists and can comment on them. When you finally really like one of the logos, you close the contest and the logo is yours. Have a look at the forums (http://www.designcontest.net/forum/).
