I'd add to this even if it wasn't 1%. Even if you're willing to give 50% or more and actually are looking for a real cofounder, make sure you provide REAL value proposition beyond just the idea. Someone posted a pretty offensive but highly accurate post recently about something like this. Might be something to look into: http://throwawayhn.wordpress.com/2011/06/10/business-cofound...

That said, I have no clue where you're from but the best places to meet a potential cofounder is usually through your own friends first, friends of friends, and then everything else. Meetup.com is a good resource, eventbrite.com is another. If you're in the bay area, there are also specific events for cofounder meetups/dating. As a disclaimer, I've never done any of the cofounder meetups/dating events or anything but its worth a shot.
