I think OP wants to hire a trader to provide trading signals to the group that OP has, That's why he's paying depending on the performance. Of course, we don't encourage this kind of method because most of us have bad feedbacks on past trading signal groups.
I think OP hired someone because the account is inactive since the thread has been posted.
That makes sense then but you should still be careful let's say you have a large amount of subscribers to your premium group and you would hire the wrong person giving, giving wrong information it might ruin your business.
