Ask HN: Who's building prototypes/ iOS apps for a flat rate?

I've seen a few posts from developers offering to build someone's prototype for a flat rate in the past month or two. Specifically I remember an apparently reputable hacker offer to do so for $5000 with the intention of helping someone with no technical skills create a functional product that can be shown to investors/etc and improved on from there. Are there more of you out there? Right now I have a geolocation iPhone app idea that I'd like to pay to have built. I live in San Francisco and am willing to work with someone from the area. Please reply here or email me if you're interested- Thanks!
