I would first write a business plan, which should help you hone your focus on your actual goal(s) and how you might best reach them. (You will need one if you want or need to borrow money anyway.) I'd create a sample budget to figure costs and potential profits. You'll likely have to do your own research to get rate ranges on insurances and the like, as they may differ across the country...same with supply costs for local suppliers near you. Being realistic and as thorough as possible at this stage could save you time, money and heartbreak down the line.
Best of luck!
