Wow. There's an industry in massive need of disruption. I'm thinking a mid-range android phone + some servos + software would do the trick. Let's say one year's dev for a reasonable engineer, so $100k + $300 in parts. Make a 1-Iraq-war-day's worth, and you'd have the unit price down to hundreds of dollars, not tens of thousands.
You'll need radiation hardening, a more precise inertial measurement unit (six axis gyro), and extreme reliability and lifetime that no consumer electronics device provides. The labor and materials cost, plus electronics mentioned above, is a lot more than $300. I also doubt you'll find a single engineer with the required aerospace and electrical engineering skills - you don't build an flight control surface control…
Reliability is obviously a concern, but the procurement process should force contractors to open their designs to qualified competitors after a certain period of monopoly profits to recoup their research expenses, sort of like the same way that brand name drugs are eventually forced to compete with generics. Just because these designs are generally national security secrets doesn't mean that the original developer should own the equivalent of an infinite patent on the technology.
