First thing you need to do is plan out your build, where you want to build it, how deep, etc. The next step is to look into the permitting process, and to do so, I suggest contacting your local building department to understand what steps you need to take next. This will include the permits you need, along with other rules on what the pool can be. I see in Wisconsin, it requires that the pool be at least 10 feet away from your home and property lines, as well, you can't be 20 feet from wells or septic systems as well. So there's a lot that goes into this. The pool will also require a fence, at least 4 feet tall or a pool cover that locks.
I know you said you want to do this all on your own, but I'd highly recommend hire contractors to do the work. They are often the best qualified and will do a much faster and more reliable job, no offense. The links below helped me find this info:
