The job of finding technically suitable locations is (as far as I know) pretty well covered: it's fairly straightforward meteorology and the industry obviously has a huge interest in getting it right, so they have invested into good tools for it, both for theoretical modeling and for in-the-field evaluation of candidates.
Harder parts are:
* navigating the conflict of interest with/impact on people living nearby, land owners/users, nature, ... to actually get permission to build and operate
* getting locations properly integrated into the grid, since they often are far away from areas using a lot of electricity.
* and of course predicting the legal and market framework for the future, to figure out profitability
