50 part time employees @ $7HR, 20HR/WEEK = $364,000 a year.
Add in the various costs of employment (payroll taxes, workplace insurance, etc.) at a low end 20%, and you are at $436,800 per year.
You still think DD just broke revenues of 1 million?
I could see disc golf manufacturers running off 5-10% margin after you include property, depreciation, costs of business. Until you go public, low margins are acceptable
