I could do your logo Check here http://fionasdesigns.webng.com/fionasdesigns/album/newlogos/?id=17631&From=1
I've sent a pm with some of my work. If you like it, let me know and I'll start thinking on a way to improve your logo.
Personally, I'd make the tagline a bit smaller, then bring it up closer to the brand name. the perhaps bring up the guy in the suite and scale him down.....play around with positioning and see what you get!
