No one makes a decent bumper for the WK. There have been several attempts to get a group buy going to have a semi-custom fab shop make bumpers for the WK (like ShrockWorks), but you need to get 20 pre-orders before it's economically viable.
The ARB is a bit too heavy and extends way too far in front of the WK, however it can be cut down and made to look really nice - but you're probably talking about $1000+ for the mods and $1000-$1500 for the bumper.
I designed and helped build my own bumper with most of the characteristics you're looking for, but it was very expensive (even with me doing 50-70% of the work). If you're in the Denver area I could hook you up with the guy who helped me fab my bumper, but it will cost at least $2K, probably much more.
Here's pics of my bumper:
