Ask HN: Where do software startups find good sales people?

Lately, I've noticed that some software/saas startups have real sales/marketing people following up on trial accounts. In fact, I've personally interacted with people from KISSMetrics, RightScale and a few others–and I think they've done a great job.

We're in a position with one product where having such a person would probably be a good idea. So, I'm curious:

Where can you find a good sales person? (Most HN posts and job boards I use are developer-focused)
