Even if you are able to get it out with the help of another developer(on contract or otherwise) it still doesnt cut it because this is just beta and there is a long way ahead for you to build a business. For this reasons, and still more, I would suggest that to take this forward you absolutely need a technical co-founder. Try to find one, and even if you have to give a very high (~40-45% stake) consider it a good deal. Additionally, 12 months is too long a time for beta. Cut down your featureset ruthlessly so that only the ones required to expose the core functionality of your site remain.
