I don't think the math works. $5k + $500/m, for 6 months: that tops out at $160,000 yearly revenue for the 20 projects. Even if it's the same 4 employees spread across all projects, that's $40k yearly salary each as a base. Sounds bad!
It'd take years for any winning bets to pay off and I don't know how you'd pay your employees.
