Should all the code be open source in Github if we are still 2-3 months away?

Is there anyone (hero member with a perfect reputation) that could maybe hold new donations in escrow as a reward for new developers to help Gnosis finish the project on a contingency basis (only getting paid upon completion)?

Gnosis, if someone were to help you, what would you need the most? Math experts? More programmers? Both? Can the remaining work easily be subdivided so multiple people can work on it at once?
