Freelance Mixologist Team

Does anyone happen to know the name of the two-man bartender team who work at events (parties, gallery openings etc.) here in Chicago? The have some great drink options - local, fresh juice mixers and offer two or three, in addition to cheap canned beer? I know this sounds kind of vague, but I can't really recall the name of their company. They had cards with a neat, old-timey font on them, but i seem to have lost the card i picked up a while back.

The last time i saw the was at an opening at the Post Family space on hubbard: http://thepostfamily.com

Any leads would be greatly appreciated.
Thanks!
