ı still do not understand why u need ICO ? The project is good enough te get privat funds. May be you should try to get investors from the privat sector who is related with the project.
It's not that easy to get a big investor or private funds . ICO is the more relibal way ,because most people who are ready to fund a whole project by themselves would want to take big share of the equity and that's bad for a new unestablished project.
