Thank you for the reply!
I've pretty much up to speed on what you described. I believe he would be eligible since he has self employment income, has no access to employer provided group health plans, it is for profit, there would be a schedule C, it's not a hobby and the business name would be the same as he name.
But there is always the fear not discovering a rule to the contrary since both my daughter and he are W2 employees besides the self employment income he has.
