I would suggest looking within your local Tech community. Search out various tech centric events through Meetup.com or look for something like a DemoCamp (or a Camp like event). Those events will attract people within the tech community that are interested in either new ideas, concepts or potentially becoming a cofounder. You could also look to see if your city has a Start-up Weekend. If you're comfortable, presenting your concept or through an event like that to see if you can match up with a passionate tech cofounder.
