I took one helicopter design class in college (I have an undergrad in aeronautical engineering), and I can tell you from horrifying personal experience that the power required to hover equation is longer than this paragraph and filled with empirical terms that vary from manufacturer to manufacturer.
In short, there is no short answer and much depends on the details of your design. If you are looking for an approximation, then look for existing helicopter designs that are similar to your configuration and check their weights and the power of their engines.
Be aware that the engines are much more powerful than they need to be to hover, even out of ground effect, otherwise the aircraft would not be able to climb. Power required to hover is not a piece of data that is easy to find.

The Sikorsky Sky Crane weighs 10 tonnes and can lift 10 tonnes. The CH-54B was powered by two Pratt & Whitney T73-P-700 4800 sph turbine engines.
