I reckon play it by ear.
Like a GFE session. If there's no one booked straight after you, then keep on going. She might even cook for you.
I wouldn't push her too much, $300 for over an hour with what's on offer is pretty good for a private. I'm pretty sure she's doing this herself without an agent or pimp.
She's a great girl and I wish her all the best. I hope she makes a lot of money.
