Why do you suppose you need to do everything, you simply need to get people interested in the idea that you're forming another blockchain, and essentially you would find those that are interested and work with them to that end. Difficult, very expensive, those sound like reasons that would fall away if you consider it's open source (free, free, already established architecture, did I mention already coded?), if you consider how many people we have in the community it's almost surprising that nobody has forked it already.
