could submit their application by getting involved in a special forum (similar to this perhaps?) that would ask them to prove themselves first by producing on a volunteer basis. Commission might even be involved.
I've always liked the idea of commission pay in government jobs. If you don't produce you just get minimum wage but those that produce get a commission that raises their pay substantially. Potentially, such a job could start right here with someone providing ideas for free. If they stand out from the crowd there would be a security check on them before any invitation and if they failed the security check they just wouldn't be invited to the next level.
