I think that the minimum limits represent is $500/week, which is represented in the following (paying 50 dollars to 10 Hero/Legendary members), and then appointing a manager will increase the expenses, but it will give better results.

You run it for one month or two then decide if you want to continues or not (so 2K-4K.)

Generally $80 per member and 20 members i.e. $1600/week will give good results if you hire a smart manager.
