I plan on telling my parents I am ready for marriage

alsalamu 3leykm I'm currently in my senior year of highschool and am ready to get married and then going to college in the US, I plan on telling my parents before the half year mark for school, I alhamdulilah changed alot of my ways to become a better, ready, and mature man, (treating people better not yelling at my little siblings and instead taking care of them and saying i love them) this does not mean I'm ready of course I also have to be physically mentally and emotionally ready to take care of another human being, I have everything planned out, all that's left is to tell my parents. Any Advice?

PS: for financial reasons i plan on going to college with scholarship and if im married my payroll is doubles, so in sha Allah I will be able to take care if my future wife.
