A franchise of a known brand is one way. You would be tutored and partially financed, but there would be a necessay up-front investment as the franchisor wants your money at risk as well as theirs. Going out on your own might present a tough bill to sell, not to mention financing the many months that you'll be losing money for, essentially, not having a customer list or even a prospect list of, for instance new home buyers or call-ins for your services. Think long and hard as unlike yardwork, you'll be selling your product on trust and little more.
