Have you though of fabbing them yourself? Do some searches on the interweb and this site for building your own TJ/JK bumpers you can find some inspiring posts I did.
Get with your local jeep club and find a welder if you can't weld, all you need to do from there is do cardboard mock up. After that you can either write up the dimensions or submit the templates to a metal company in the area and they can cut them for you.
Key thing for you to remember is that for a full blown 2" receiver hitch to be incorporated to the bumper it needs much stronger connectors than the typical bumper mounts, but if you design your own you can easily account for that.
As for factory mass produced items I have never seen a bumper with a towing qualified receiver.
If you own it, wheel it
. If you don't, buy it, then wheel it. Get Dirty
