Advice for new owners

I’ve been in customer service and other areas for years including public safety, but I am still trying to figure the best way to start/set up my business. I understand the management process, logistics side and other aspects following that including being an intern. I guess what I’m asking is if someone can give me advice on that area to help broaden my horizons and vision of owner/employee I should say. I am looking into the home services side, ie lawn care, landscape, concrete, pressure washing, outdoor construction (gazebos, arbor), etc. I’m open minded accepting and grateful for any advice or criticism from everyone. Thank you in advance.
