Um, your wife and co-worker are right. This is not how to hire women.

Also I find it interesting that you were considering a woman for job as a UI designer. Why not another engineer?

Here is a potentially better way to do it. Is your female co-worker comfortable presenting in public? If so, have her give a technical talk with cool demos and say you're hiring. That's not a bad way to find potential employees. And if there are women available, seeing a female face of the company will make them more interested.

But if she comes back with a smart guy, hire him. Because you're looking for a good employee first, and not a woman first.
