New and experienced are well advised to check the Support And Advice For Escorts website. This website is run by escorts and contains good advice. The site also runs a forum where warnings about dangerous clients, and violent criminals preying on sex workers are posted.
You may also want to help other escorts joining the industry, or if new to escorting seek advice from a buddy. There is a scheme called escort buddys. This scheme is run by an escort, the aim is to pair experienced escorts with inexperienced escorts for advice and someone to chat with.
