Good on you to take the leap. The ppm depends on the girl and what she considers her worth to drop the panties for you.
The Sydney market is usually from 500-1000. My meetings have been from 400-700 so far. I thought the 700 I could form some connection and be able to reduce price after some time. But this was a professional and after taking the money started saying 2 hours limit and she has sex only once. She wanted 1k for two times. She did not do bj either. I had more fun with 400 meetups than the 600 and 700 I have paid on the past.
