Google the musicians union and see what they actually cost, not what you want to pay. Then take your 6k (assuming you sell out) and subtract those wages, minus the marketing, minus the venue fee, minus the venue labor, minus the insurance, minus the royalties for whatever music they play.
Good luck
Any real angel investor will balk at your projections. Sorry dude, pretty unrealistic regardless of industry. Also, if that’s really accurate and you’re offering up that much of your company you lack the business acumen to lead this enterprise. Not trying to be a jerk but that’s just the reality.
