business startup

Hi my name is Marin. I am from Croatia.Currently i am studying management but for the last 8 years i am interested into rocket and I was learning about it by myself and was the best in 20 years in technology tests. From 2019 to 2020 I was designing my own rocket and I want to raise funds and start up a business with production of my own rockets and other product that i hope to export to other countries. second thing is that I can hire more people and in that way help to reduce unemployment.I would be infinitely grateful to everyone for any help. Greetings from Croatia.
