Webcam show booking sites

[sommer]

Are there any websites where models can offer webcam bookings, similar to how adult work used to offer the booking facility?

Eg.

1. Member books show for date/time/duration
2. Makes payment (held in escrow for 24 hours)
3. Do cam show via Skype, FaceTime or other video call app of choice

Is there anything like this exists?

Ps. Not talking about Skype plugin like Skyprivate.
