Lawn care buisness start up

Hello my name is Nick and I am 25 yrs old.I would like to start a lawn care buisness for multiple reasons but mainly the fact me and my step father use to cut grass together when I was young.But,do to his drug addiction his life was cut shoraft 33 leaving behind my little brother and sister without a father.I hope to establish par good buisness that my brother and sister can one day take over.Because they have learning disabilitys which may refrain them from regular employment in most cases.
