This is just a start...
OP, when you register for the tournament, you provide the roster/ player cards at that time of registration.
For all the Girls that are already playing Travel, you will have to reach out to their teams to get their Player Cards. (Futsal Clubs do this in the Winter Time).
For Girls who are not in Travel, you need to create Rec Passes for them.
You will have to create a Got Sport Account to enter in all the Team Admin Data in order to get Rec player cards.
For VYSA, you might want to contact the State Registrar, info here:

If you are in Virginia, VYSA has a Rec roster template:

Give the registrars a call and they could likely walk you through the process.
