I am a programmer, not a designer. I want to be able to quickly get out landing pages to test the market interest on my ideas, however, from my experience on HN, the quality has to be very good. And the examples are always design heavy. Is there a service, other than elance etc., that specialises in making landing pages at a reasonable cost? In the effort that I specify my idea to them, then they go and design the landing page, perhaps with a video and make it look awesome?

Otherwise, elance it is!
