As someone else said you will have to buy a company or accounts to be a "business owner" out of the gate. Otherwise it will take years to build the accounts. My father retired from corporate life and had a buddy talk him into financing a lawn business. He put in over 300k to buy a business which already had crews mowing the yards. His buddy soon after bailed and he was left holding the business. He had no horticulture experience and the business tanked by about 30%. It eventually leveled off, but it was not something he wanted to continue with. The heat, the hassle, the pain in the ass customers, etc. it's not all gravy and a cash grab. If you have 300k to invest, you'd be better off investing in another type of business. I do this work because I really enjoy landscapes. I enjoy the freedom of being my own boss, but at the same time the business is the boss of me.
