Affordable prototypes make sense, but what about the $500 level setting false expectations for the cost of the production-quality app? If you're pitching this at non-techies, you'll also have to get them over the hump of realising that a lash-up is easily an order of magnitude cheaper than a decent, real-world-robust version. "Hey, WTF are you doing quoting me £5000 for a full build of this app? I had the prototype done for $500 and it does almost as much as the real one I want."
