vaksel is right. I've seen recommendations on here before about different sites to find tech co-founders and seen the "go to tech meetups" advice. But the real problem is that the programmer you want probably already has his own pet projects. If you want a tech cofounder, you should pay him to develop a prototype.
As a business co-founder you're probably not doing much in the early stages. You come with an idea, which is essentially worthless without the tech guy. So it's only fair that you pay him for the prototype. At that point, both of you will be more comfortable teaming up.
Also, I would make sure you have the tech guy assign any and all IP ahead of time. You'll need this assignment if you want to raise money in the future.
