How to Start a Landscaping Business?

Im very interested in having landscaping as a career. I understand that there are many people in this industry, especially people that just mow lawns, but I am willing to start small and cheap, and learn more and more as I go. I'm 19 years old now, and I know Im too young to start it, but i plan on building up my experience by mowing lawns starting very cheap, and growing a list of clients. I have no actual experience, no money, and only a push mower, electric weed eater, electric hedge cutter and shovels/rakes. Do I need any more equipment to start off small? Maybe an edger? I dont have a trailer for my stuff, only a car that i can use to put the mower in the trunk. How do I get my first client? Or any at all? I dont know anyone that I can start off asking besides strangers, and I dont even have a yard of my own anymore. How do I Start? How many clients should I work up to? Id love to work for a lawncare business for experience, TruGreen is hiring for example, but they want you to be 21 (i dont understand why). After Ive become old enough and have enough clients, maybe some more equipment and experience, whats are the steps to actually making it a real Business? After just mowing lawns what do I branch off into? What do i charge per lawn? I want to keep it cheap at first to guarantee me the job or I wont get any experience or clients, like 20 dollars a yard if it isnt huge. When im 21 should i get a loan and buy a few more things equipment wise, get a website etc? Lets just try to not include how old I am, and answer the question: How Do I Start A Lawncare eventually Landscaping Business From Scratch With No Experience Or Money, part time at first because I work a second shift job. I appreciate absolutely Any advice tips information and answers. thank you
