The problem with most clubs is they are unused most of the day and can only make money at night for a few hours, usually only 2 nights, Friday/Saturday. That means they must pack the place and make as much as possible from cover charge and booze sales. That's a tough job to pay all the rent, salaries, heat, power etc from just a few hours of prime-time clubbing each week.

I think the answer could be to use a space such as a restaurant that is suitable for club activity. It can make an income from food sales or other activity during the day. Then on the club nights the main activity such as restaurant is shut down, tables & chairs are moved out of the way, turn on the disco lights, fire up the DJ audio system, and you're into club mode.

Since you don't need to make a lot of profit from the clubbing time, you can reduce the cover charge. I wouldn't reduce the drinks prices too much because that just brings in the boozers who aren't really there for the music.
