Between 20K and 40k almost every day,
So being conservative an average of 26k per day.
Each person seeing 8 1hr or 16 0.5hr clients earns 1600 half of which goes to secretary.
He gets 800 per subcontractor per day. Roughly 33 people.
Plus more to cover living expenses, rent, travel. As much as possible these paid using cash to prevent the need for moving money through accounts.
Conservatively 40 subcontractors.
Likely to be more since that estimate assumes busy traffic.
