Hey!   Interesting question.  Just looking for some amusing new performers, huh?  Well, I'm not much help, with only a small passing knowledge of a handful of comics I've seen highlighted here and there, mostly due to being famously popular (although I always thought George Carlin was pretty funny).  But.  I just had to throw Jeff Dunham's name in the list, if someone was bringing up stand-ups, cuz he's awesome.  Came across him by chance some time back on you tube (or maybe your library/netflix has duds), and while some of it may be a bit of 'adult humor', it's never R-rated, or tons of swearing.  Just a really funny guy.  With his 'puppets'.  Not sure what kind of stuff Hills covers, and I know Jeff's kind of act might not be for everyone, with not being "purely" stand-up (if that's the best way to say it) or some subject matter but still good.  Hilarious how he and his puppets each have their own voice, break the fourth wall, make fun of each other, and in general, goofy.
Here's one of my favorite/best clips of him with the funniest puppet of his entourage, for an example:  http://www.youtube.com/watch?v=oQm_8vX3sYU
