How should I finance my risky capital investment

It is going to take 12-18 months to get approval for the food products we are going to produce. It will also take at least a year to build the factory. How can we finance all of this?

If we do not get regulatory approvals, then the factory is useless. If we have to wait 6-12 months, we are going to have to give a away a lot of the company to get the working capital we need.
