Good luck. I am in the same situation.
I had a promising lead coming out of my submission (http://news.ycombinator.com/item?id=2320490), but it did not work out due to conflict of schedules. I hope that you will be able to find someone. Best of luck.
Thanks. Yeah, we originally had somewhat of a technical cofounder who did great work for us. He, ultimately, had a lot of other stuff on his plate...so it didn't work out. It's a lot harder to move forward than I thought without one.
Someone good will always be in high demand. Edit: How about going to campuses around Chicago and posting an add for a co founder? There may be a Zukenburg type of a kid out there waiting for his potential to be discovered? Also, they may be willing to devote a lot of time to the project. Just have them sign an NDA...:P
