This actually a good idea!
But I think we should pre approve a budget and specs (via DAO vote for ex) for a given project and publishing it like a bounty hunter job board.
Then devs or studios can start working on the project and directly get paid when the product is delivered.
It cannot apply to all types of jobs, especially "background" tasks like maintaining code but it could be very effective at getting new concepts implemented rapidly and efficiently.
That sounds very good.
